Pythagorean Theorem

What?? That's what I said today during practice. I'm proofing what with this material?? It has been a while since covering this in Geometry- but just to catch you all up on this material, I have provided you with a description.

The squares built on the two legs are each equivalent to parallelograms which together are equivalent to the square built on the hypotenuse. The rectangle, the square on the hypotenuse, is thus the sum of the squares on the legs.

Now all I have to do is guide a child to discover the theorem. Can I do this??? Let's hope so- because I'll be teaching very soon.
