A quadrilateral with both pairs of opposite sides congruent is a parallelogram.
Yes. A parallelogram is a quadrilateral in which both pairs of opposite sides are parallel.
Every quadrilateral has four sides and they are opposite each other. So, ALL quadrilaterals have both pairs of opposite sides.
A parallelogram has two pairs of congruent sides, and the opposite sides are 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.
If both pairs of opposite sides are the same length, and both pairs of opposite angles are the same, the quadrilateral is a parallelogram (rhombus, rectangle, or square).
