When using the given diagram, the following steps prove the Pythagorean theorem.

Step 1: Given yellow triangle abc

Step 2: Construct 3 triangles congruent to yellow triangle abc.

Step 3: (a + b)2 = c2 + 4(12ab)

Step 4: a2 + 2ab + b2 = c2 + 2ab

Step 5: a2 + b2 = c2

A)4(1/2ab)
B)12ab
C)ab
D)2ab
