Ab is parallel to cd. cd is rotated 180°. which statement describes the relationship between c'd' and the transformed ab? how can you prove it? a) c'd' intersects ab; graph the points to find the point of intersection. b) c'd' || ab; use the slope formula to prove that the segments have the same slope. c) c'd'≠ab; use the distance formula to prove that the segments are not the same length. d) c'd' ⊥ ab; use the slope formula to prove that the segments have opposite reciprocated slopes.
