Are the opposite sides of a parallelogram supplementary?

Yes, the opposite sides of a parallelogram are equal in length, but they are not supplementary. Supplementary angles refer to two angles whose measures add up to 180 degrees. In a parallelogram, consecutive angles are supplementary, meaning each pair of adjacent angles sums to 180 degrees, while opposite angles are equal but not supplementary.
