A parallelogram is a quadrilateral with opposite sides parallel and congruent.
For the quadrilateral to be a parallelogram, both pairs of opposite angles must be congruent.
No, it doesn't have to be. A quadrilateral can definitely be a parallelogram only if: - Both pairs of opposite sides are parallel. - Both pairs of opposite sides are congruent. - One pair of opposite sides are both congruent and parallel. - Both pairs of opposite angles are congruent. - The diagonals bisect each other.
