Paper-folding proof of Pythagoras
Here's a great video by Vi Hart that shows a couple of proofs of the Pythagorean Theorem. Nothing new in terms of the proofs; they're ones I've seen often. What's clever about Vi's approach is that she uses paper-folding to create the elements of the proof. I like this kinesthetic approach to a couple of familiar proofs.
As always with Vi's exuberant videos, it would be nice to be able to watch them at half speed!
Enjoy!

the proof is nice but it is little fast
