## 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!

I like this proof of the Pythagorean Theorem. Thanks

the proof is nice but it is little fast
