In using the figure below to prove the Pythagorean Theorem, which statement would not be used? A The area of the large square is equal to 1 2 (a2 + 2ab + b2). B The area of the large square, less the area of the smaller square, is equal to 4 ( 1 2 ab). C The four triangles are all congruent. D The area of the smaller square, c2, is equal to a2 + b2.
I think its A. but it could also be B.
