Answer:
D. Consecutive angles are congruent
Step-by-step explanation:
I think it should be "Consecutive angles are supplementary (add up to 180-degrees)." Correct me if I'm wrong, Hope it helps>,<
Step-by-step explanation:
If the four sides do not connect at their endpoints, you do not have a closed shape; no parallelogram! If one side is longer than its opposite side, you do not have parallel sides; no parallelogram! If only one set of opposite sides are congruent, you do not have a parallelogram, you have a trapezoid.
