Question
Consecutive angles of a parallelogram are _____________. (supplementary, complementary).
✓
Answer
Consecutive angles of a parallelogram are supplementary.
Explanation: Let $ABCD$ be the given parallelogram.
Thus, $AB || DC.$ Therefore, $\angle\text{A}+\angle\text{D}=180^\circ$
Consecutive angles $\angle\text{A}$ and $\angle\text{D}$ are supplementary.
