Question

explain the property of a parallelogram?

Answer 1

opposite sides are equal, opposite angles are equal, the diagonals bisect each other, the sum of any two adjacent angles is 180 degree

Answer 2

Opposite sides are congruent (AB = DC). Opposite angels are congruent (D = B). Consecutive angles are supplementary (A + D = 180°). If one angle is right, then allangles are right.
