If consecutive angles of a quadrilateral are supplementary then the quadrilateral is a parallelogram?
True
Are complementary angles consecutive angles in a parallelogram?
The question does not really make sense. Once might ask, "Are consecutive angles in a parallelogram complementary?" in which case the answer is no. Complementary angles are angles which add up to 90 degrees. Consecutive angles are angles next to each other (or follow each other). In a parallelogram, consecutive angles are supplementary (add to 180 degrees). In a parallelogram, opposite angles are equal. You could have a parallelogram where two angles are 45 degree (and thus complementary) and then the other two angles would be 135 degrees.
If all pairs of consecutive angles of a quadrilateral are supplementary the the quadrilateral is a parallelogram?
