Question

The figure below shows two triangles EFG and KLM:

Which of the following can be used to prove that triangle EFG is also a right triangle?
Select one:
a. Prove that a + b is greater than c in triangle EFG so c2 = a2 + b2.
b. Prove that the sum of the squares of a and c in triangle EFG is greater than square of b in triangle KLM.
c. Prove that KL = EF so in triangle KLM a2 + b2 = c2.
d. Prove that KL = EF so in triangle KLM c2 = a2 + b2, which makes triangle EFG a right triangle.
