Looking at this proof of the Pythagorean Theorem, which statement would be true?
a
The length of a is the same as the length of c - (a+b).
b
The yellow triangles have an area of a x b, which would = c
c
length of a + length of b = length of c
d
The area of the 2 small green squares on the left have to be equal to the area of the large green square on the right.
