A fascinating, beautiful and educating puzzle! Moreover, all this is a proof of the celebrated Pythagorean Theorem without any formulas!

Well it would be cool if there were more square puzzles but there is only one and it's always the same. In my opinion it's a waste of space. =\

A right-brain way of proving the theorem

I would definitely recommend this app to any parent who has a child in school. Imagine how much simpler theorems are to understand when you can actually see how they work. My 4 year old knows the theorem now (no, he's not in Mensa).
