Why do the angles in a triangle add up to 180°??

Описание к видео Why do the angles in a triangle add up to 180°??

My goal on this channel is to make short, easy-to-understand videos exploring topics that we may have just memorized to be true but never actually proved. Have you proved before why all the angles in a triangle always add up to 180 degrees? Can you think of any other ways to prove this?

Whether you're already a lover of mathematics, or you're someone who thinks math is the farthest thing from "cool", I hope you stick around, learn something new, or just find something to appreciate about the mathematics all around us.

Tell me what other proofs or videos you'd like to see on my channel!
