Question

complete this sentence by selecting always, sometimes, or never.
pairs of consecutive angles of a parallelogram are ____ congruent.
after you pick your answer press go.
a. always b. sometimes c. never

Explanation:

In a parallelogram, consecutive angles are supplementary (their sum is \(180^{\circ}\)). For them to be congruent, each would have to be \(90^{\circ}\). This is true for rectangles (a type of parallelogram), but not for all parallelograms (e.g., a non - rectangle rhombus). So, pairs of consecutive angles of a parallelogram are sometimes congruent.

Answer:

B. sometimes
