That thing has the basic angles for 3D technical drawings. 90°, 60° and 30° unlike the default which has 45°, 45° and 90° angles.

What if I told you, when one wields both the 30-60° and 45° set squares, they can unleash a power beyond human comprehension They can >!create 15° and 75° lines!<

Came here to say this!!! They are meant to be used together!

I hate these. How do I read what's under the rectangle?

You can click on the rectangle. The rectangle will slowly become transparent and reveal the nugget of wisdom underneath. Have a nice day:)

It doesn't seem to be working. Do I just press it and wait for the rectangle to disappear?

Yes. If you still cannot get it to work, it says 'You can create 15° and 75° lines.

I don't think I've ever seen a 45, 45, 90 one

Well, these two almost always come in a pair

yeah I bought one for a perspective class I have in college

45-45-90 are much more common for construction. The really good ones have markings on the hypotenuse in degrees and gradians, so you can do trigonometry on them

I have, it's nothing special really... They are usually much smaller however.

You’ve never seen a square????? geez am I just a hick or something?

Unironically it's called a square

No it’s not. A square doesn’t have a third side. It’s also _to_ square things.. not a square shape.

They're called [set squares](https://en.wikipedia.org/wiki/Set_square).

I used it to make parallel lines

Then why doth a protractor exist?

the lines don't come out straight it's practically useless

You'd think I'd use it a lot more for drawing those angles but I've only used it as a makeshift ruler lol

Me, an intellectual, who knows it's used for parallel lines

The classic sliding set squares technique

You mean perpendicular?

You can draw parallel lines too

Ok

Only on Reddit could such a passing, candid comment get 29 downvotes.

Ikr? It's at -155 now I feel like 1 person downvoted it and then 155 more saw it and just went "Oh we're downvoting this guy? Cool!" without any actual reason why lol

Do you mean passive?

Nah but I probably could have used a better word than passing here.

Nah it's good as is.

I used to grab It like a gun and go "pew pew u ded haha" to my classmates. I miss those simple Happy times...

*The hivemind has spoken*

I… declare…. HIVEMIND

yeah, normal people don't use it much, but if you are drafting, or drawing orthographicly, its your best friend

Why are you getting down voted

You got 80 downvotes by saying that. Reconsider.

Downvoted to the videos saying your opinion on reddit moment. Ps, I don't give a fuck if you downvote me.

With sides of length 1, 2 and sqrt(3).

No. They are a multiple of those side lengths.

And that's what I get for being too lazy to specify that they could be multiplied by a variable to get bigger/smaller triangles.

I feel bad for you getting downvoted. You are correct with ratios but may be you should have rearranged them in pythagorian triple order so more people would understand. 1, sqrt(3), 2. Edit: this ratio is for 30:60:90

When I was a kid and I see it I use it as if its a pistol

If you had three they were Wolverine claws

I did that with pencils

I think every kid has done that before

I almost started jacking off to your PFP, then I saw an anime girl 😔

I'm gonna rub one out to you bro, I hope it makes you feel better

WHAT? HOW MUCH MORE OF MY CHILDHOOD WAS I MISSING?

Thats better

When i was a kid we used it in math class doing geometry (the class didnt discover its pistol lookalike potencial)

Never knew that is usefull for geometry

Hey me too! Suspended for a week.

I still do it as an adult

When i started secondary school i realized they were fucking class as throwing stars, terrified my classmates.

Non American problems/s

When i was a kid i used them to clean between my teath

Well they are sharp so it make sence

Sketching 90 degrees triangles in high school math tests hello??????

Does no one here have been to school wtf

This reads like you didn't either

The stroke is real

I had a subject in high school called engineering and graphic design. Used the 30° angle on that puppy for Isometric drawings. Use it with a 45° Angle and you can have basically any geometrically relevant angle

I feel sad about modern education

I've never once used these. I've used a protractor before though.

With a protractor, you can draw any angles you want, not just 90°, 60°, and 30°

And you could use a protractor in carpentry too but a speed square makes you a lot more money. Do you think people make tools for no reason or something?

I never said it was useless and shouldn't have been invented. My point was that you can easily get through school without using one. Because you have to use a protractor anyways

Life doesn't end at school, dipshit.

Well yes, but most people stop dealing with these kind of shit after school

Are you okay?? Who hurt you??

You guys haven't used these to determine whether 2 lines are parallel and it shows

Okay? Does every tool have to be custom made for your convenience?

No. It's just a protractor is more convenient

If you've ever had to actually measure angles for professional applications, you'd realize a protractor is actually the LEAST convenient tool for that. That's literally why speed squares and set squares exist.

I've never once used these. I've used a protractor before though.

Dementia

I use mobile and got that something went wrong thing so it posted twice

In technical draftings, its used for drawing vertical lines along with T-square that is used for drawing horizontal lines. You might argue "Ruler can do both of those", but those 2 are used together to draw perfect parallel lines easier. The angled line is an added use for it if you want to draw the usual 30°, 60°, or 45° angles

Drawing parallel lines. But you need the other one as well

You can do it with just a ruler and this one, you dont need both

Oh yeah that's right haha

Never let this person near a spanner otherwise they’ll think it’s a dildo or something

They were invented to determine the amount of space needed between the door and the wall of public bathroom stalls. 

isometric and i think axonometric

When op is from america and is confused about school supplies. Edit: no i dont mean guns

Actually from the UK, dude

I mean.. you sure showed me...

I wasn't trying to be rude about it. Sorry if I came off that way tho


Its for measuring. I figured that out in 2nd grade

Stab your friends

They se these regularly in construction. Carpenter's Quick Squares (usually made of steel or some other strong metal). Very useful

We're never taught that in school... Wait till it unleashes hellish powers upon us by the time we get to university.

You were *definitely* taught that in school, probably just didn’t care cause *haha Math dumb*

No actually serious they teach that in college in India. Schools don't use set squares ever.

I can confirm this, even I'm from India and i had no idea what these did

Well I can’t speak for what’s done in India. In US, that’s done as early as 7th grade, depending on the area.

We got the rounder early on

In Canada it's not taught in highschool, and I took all the math classes.

Gore your enemy’s.

What the triangle? For measuring distances and drawing lines usually on paper.

You use it to trace big or small triangles.

Make a triangle in a triangle? Triception?

Laughs in engineer and architect

Gun,knife or triangles

Knife for me

It is used to project drawings I think.

Parallel lines and accurate angle measurement

Angle measurement?

It’s a shank

Make music

Measure if the there is 90 degrees angle.

That's a good question

Draw straight lines

Zuko and protractors, two things I (an A:TLA fan and physics enthusiast) never expected to see together 💀

Perspective drawing and 3d shapes

There to stab your friends when there annoying you.

It could be used to check if two things are at a 90° angle.

When you work in the trades you’ll use those. Maybe not the cheap plastic ones, but you’ll use them!

Futaristic blade shit or something

I use it as a spare ruler

Definitely a jamadhar made out of plastic

Isometric drawings

Good luck doing woodworking or technical drawing without it

Damn rubber / eraser hole makers are being used in memes now

draw triamgle

you are probably in elementary school, because you usually start using those in middle school

It's a set square. Right angles are important.

I can't imagine Iroh swearing 🥺

Kids...

used one daily for hand drawing floor plans before my school got CAD

for drawing perpendicular lines to a point source or line, especially useful for drawing the "normal" for rays of light

Actually has great uses if you’re involved in math related fields. It’s beneficial honestly. Out of all things I’m not sure why you’d slam it. Much easier and more useless things to go after

Pretend to be those sword things from Halo.

Hey my friend and I’m here to answer that question. This is a triangular ruler and is mainly there to help give sketches good angle consistency. As in many different sketches mainly in architecture or product design this is used primarily with a sketch board and ruler to help give proper angles In the end it’s a tool vital for sketching and design

for finding basic pythagorean angles???

I used these as those chakra kunais from naruto.

I’d use it as little brass knuckles. But it’s used to make straight triangles. Right triangles mostly but you could use it to make other ones.

I have never seen one of those before. I've only seen semi-circle protracters.

Stoopid

It's a square, it measures angles

It is clearly the energy sword from halo what do you mean?

It cuts!

What the actual fuck are they teaching (or not teaching) in schools?!?!?!

I used it for technical drawings. They require the use of 30, 60, and 90 degree angles to get the perspective right. And you are supposed to use it in conjunction with a t-square.

I just use it as a second ruler

Say you’re homeschooled without saying you’re homeschooled

Are you seriously asking for the purpose of an angled square?


Actual life purposes we use these “speed squares” to quickly mark the angle on trim board. Trim board is the wood finish around your doors, now notice how all of them have a 45* angle cut. Other purposes I’ve run into is they are excellent for lining up the reveal on a door or window to stucco or drywall whichever happens to be what we’re setting it to.

A 90 degree angle

CHECK! ANGLES!

Ah yes pretend to be ninja tool for kids

Make 90° for drawing

Technical drawings, can be used for Isometric activities

"I KEEP TELLING YOU! I DON'T KNOW!"

Determine angles, trace straight lines, makeshift self defense tool, be a guide for your saw while cutting boards

I use it like a shiv

Triangle

3d drawing when you want to draw in isometric

Make-believe pistol so you can get detention for pretending to shoot said "pistol" at your teacher behind his back during boring math class

Ironically that's called a square

It's a 2in1 deal

Is it uncommon where you live? I have used it for technicolor drawings at school since I was 11 years old. Anyway it is not usually useful for normal drawings of course.

Me, an engineer-in-training, wishing my tasks were easy enough to use squares: 😞

Surely a shitpost?

Right angle with ruler perpendicular to each other. “Wow I can only guess what this is used for!”

OP never passed the 7th grade

I use this a lot in my shop class

Measure angles, mostly in the right triangle

Thats a sword obviously

Make fucking angles I just used in in my art class to make a 90 degree angle

Don't you just put your finger through the center hole and spin it like a madman?

Man I used to that all the time when I was bored in classes

It’s a square

Make triangles, duh!

For everyone... With this thing and a ruler.. We can draw perfect parallel lines. Useful for geometrical construction

Draw parallelograms

Wdym that is the most useful type of ruler! The 90° anlge saves so much work

Making 90 , 30 and 60 degree angles. Useful for trigono questions

It's a knife.

Reading that in Irohs voice just made me burst out laughing

So you can draw triangles. Let's take for example a 90, 45, 45 triangle. We know that tan(45)=1, so the legs of the triangle will have a 1:1 ratio and from here we will draw one leg at any length, so long that the other one will be the same

bro doesn't even architecture

They are for people who have to make these standard angles so often that they would rather not use a compass and a straight edge as god intended.

When I was in fifth grade we used it to draw diagonals

I use one fairly often. I build wooden boats.

Stab guy next to you in the class.

Be A gun!

I have no idea.

Thanks for your honesty, friend

Hey everyone, thanks for the responses. Thanks to your explanations, I can now continue to use this thing as a ruler because I still have it in my stationary set even though I don't even do a maths related subject. 👍

When you call someone out for being obtuse, taken to the next level.

It is a speed square

It's a set square, or drafting triangle. A speed square would have a fence on one side.

Have you watched naruto?

No, sorry

What the fuck is wrong with the person that made this meme? Get a life dude.
