Pythagoras

Today's comic includes a proof of Pythagoras's theorem. Enjoy!

Pythagoras

Pythagoras's theorem does indeed have a lot of proofs. Wikipedia list some of them here. This theorem is really important, and yet it gets taught without showing students a single proof. This theorem has a broad range of applications, mostly in trigonometry. it is also an important theorem because it was one of the first theorems to be rigorously proved.
