I never knew this had a name! I discovered this during GCSE maths - it annoyed my maths teacher.

ok now you're just saying cumbutt
If this was how geometry was taught, not just the facts, but an intuitive lesson on why the facts themselves exist, I think a lot more people would pay attention.

is it rare for me to say that ive watched vsauce' videos way to oant times

It's actually impossible to create parrell lines because nothing could be absolutely straight it can still meet with the other line but it just won't be shown on the piece of paper

Why didnt you just measue the diameter and half it th ofind the centre instead of drawing it twice ?

I'm a computer science student and have a calculus exam tomorrow. it looks like I gotta watch a ton to catch up the theorems in m my class. but joke aside this is a great video that I'm so sad I couldn't watch these when I was a child.

This sums up literally everything I learned in Geometry

I found it crazy that I was taught about everything Michael talked about in this video in 7th grade (maybe 8 or 9 I'm not really sure). And I thought that everything was really obvious but then he explained everything in such detail and I really appreciate that. Also I'm pretty sure this video is not made only for kids.

My dude is being so family friendly he censored compass and is still getting demonitized. YouTube broke
literally what
this entire video is just a high school geometry class, and i’m here for it
Fe Simco
Cumbutt seems grosser
Thales Donizetti
You're welcome.
Halfway the video you don't know what he was proving in the first place
THIS MAN kept his joke of combutt for at least 19:30 seconds. tf I love you
