What is a quadrilateral with 2 pairs of opposite congruent angles?
a parallelogram
If one pair of opposite sides of a quadrilateral are congruent then the quadrilateral is a parallelogram?
No, you need both pairs of opposite sides to be congruent (i.e. the same size) to be a parallelogram.
If one side of a quadrilateral is congruent to its opposite side then the quadrilateral is a parallelogram?
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.
