# Pythagorean theorem Proof.

It is given that A^2+B^2=C^2. This is only true for right triangles. This is true because the legs of a triangle A and B equal the Hypotenuse which is C. For example if A is 3 you would square that and then you would add that to B which is 4 and square that to get the hypotenuse which is C.
