    There are six important properties of parallelograms to know:

    Opposite sides are congruent (AB = DC).

    Opposite angles are congruent (D = B).

    Consecutive angles are supplementary (A + D = 180°).

    If one angle is right, then all angles are right.

    The diagonals of a parallelogram bisect each other.

    Each diagonal of a parallelogram separates it into two congruent triangles.
