Which triangle has hypotenuse Side G F? A cube. The top face has points A, B, D, C. The bottom face has points E, F, H, G. triangle AFG triangle BFG triangle EFG triangle DFG
FG is apparently the diagonal of square EFHG. In order for it to be a hypotenuse, the vertex of the right angle of the triangle must lie on a sphere of which FG is a diameter. The only vertices of the cube that so lie are points E and H. Only triangle EFG is among the answer choices.
