Question
I need help writing a critique of this proof
Draw a square ABCD with side = a + b. Let E, F, G, and H be points on each side of the square such that BE = CF = DG = AH = a. First, notice that Area (ABCD) = (a + b)² = a² + 2ab + b² Second, observe that the area of the square ABCD is also equal to the area of the square EFGH plus the area of triangles ABEH, ACFE, ADGF, and AAHG. Thus, A ab Area (ABCD) = 4 + c² = 2ab + c² Therefore. 2ab + c²=a² - 2ab + b² → c²=a² + b² plis a G 9 C
