Question

Parallelogram ABCD is shown. Which statement is correct? A) ∠A and ∠B are supplementary. B) ∠A and ∠C are supplementary. C) ∠B and ∠C are complementary. D) ∠B and ∠D are complementary.

Answer 1

A). ∠A and ∠B are supplementary.

Explanation:

Answer 2

Answer: (First answer choice) angle A and angle B are supplementary

One rule in any parallelogram is that the adjacent angles (ie angles that are next to each other) add to 180 degrees. So that is why the adjacent angles A and B are supplementary.

Another rule is that the opposite angles of a parallelogram are congruent.
