Given: △abc is a right triangle there are 3 shaded squares with sides a, b, and c, respectively. a, b, and c are also the lengths of the sides of the right triangle, such that the area of the square with side a is a2 and the area of the square with side b is b2 and the area of the square with side c is c2. prove: a2 + b2 = c2 (pythagorean theorem) proving which of the following will prove the pythagorean theorem? a when you subtract the area of the smallest square from the medium square the difference equals the area of the largest square. b the sides of a right triangle are also the sides of squares. c m∠a+m∠b=m∠c d the area of the two smaller squares will add up to the area of the largest square.
