Pythagoras Theorem by an Iranian Girl

What follows is a facsimile of a proof of the Pythagorean theorem by a 14 year old Sina Shiehyan from Sabzevar, Iran. It is simple and elegant. It is clearly related to Euclid's VI.31, but Sina's derivation is quite independent.


This is now proof #67 in my collection.
