If a quadrilateral has two pairs of opposite congruent sides, then the quadrilateral is a parallelogram.
A parallelogram. Opposite sides are parallel and congruent.parallelogram is a quadrilateral with two sets of parallel sides. The opposite sides of a parallelogram are of equal length, and the opposite angles of a parallelogram are congruent. The three-dimensional counterpart of a parallelogram is a parallelepiped.Parallelogram - A quadrilateral whose opposite sides are parallel

(1) Parallelogram A parallelogram is a quadrilateral with two sets of parallel sides. The opposite or facing sides of a parallelogram are of equal length, and the opposite angles of a parallelogram are equal.(2) SquareA square is a regular quadrilateral. This means that is has four equal sides and four equal angles.(3) RhombusA rhombus is a quadrilateral whose four sides all have the same length. Opposite angles of a rhombus have equal measure. The two diagonals of a rhombus are perpendicular.(4) RectangleA rectangle normally refers to a quadrilateral with four right angles.ParallelogramSquareRhombus

If a quadrilateral has two pairs of opposite congruent sides, then the quadrilateral is a parallelogram.
A quadrilateral is a polygon with four sides. A parallelogram is a quadrilateral in which the opposite sides are parallel.
No.
No. The only conditions to quality as a parallelogram is that it is a quadrilateral, and that opposite sides are parallel.
Yes. A parallelogram is a quadrilateral in which both pairs of opposite sides are parallel.
Then, the opposite sides are congruent.

A quadrilateral is a parallelogram if it has two pairs of (opposite) sides that are parallel.
The opposite sides of a parallelogram are parallel lines and a parallelogram is a 4 sided quadrilateral
Theorem A: A quadrilateral is a parallelogram if its opposite sides are congruent. Theorem B: A quadrilateral is a parallelogram if a pair of opposite sides is parallel and congruent. Theorem C: A quadrilateral is a parallelogram if its diagonals bisect each other. Theorem D: A quadrilateral is a parallelogram if both pairs of opposite angles are congruent.
