The measures of the adjacent angles of a parallelogram add up to be 180 degrees, or they are supplementary. Then, AD ∥ BC and AB is a transversal. ... Thus, the sum of any two adjacent angles of a parallelogram is 180°. Hence, any two adjacent angles of a parallelogram are supplementary

The parallel line conjectures will help us to understand that the opposite angles in a parallelogram are equal in measure. ... The measures of the adjacent angles of a parallelogram add up to be 180 degrees, or they are supplementary.A Parallelogram is a flat shape with opposite sides parallel and equal in length. Angles "a" and "b" add up to 180°, so they are supplementary angles.
