Yes. A parallelogram is a quadrilateral in which both pairs of opposite sides are parallel.
A quadrilateral is a parallelogram if it has two pairs of (opposite) sides that are parallel.
No, you need both pairs of opposite sides to be congruent (i.e. the same size) to be a parallelogram.
A parallelogram.
Equal and parallel
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.
Yes. A parallelogram is a quadrilateral in which both pairs of opposite sides are parallel.
Then, the opposite sides are congruent.
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
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.
Parallelogram
A quadrilateral with both pairs of opposite sides congruent is a parallelogram.
No, you need both pairs of opposite sides to be congruent (i.e. the same size) to be a parallelogram.
A parallelogram is a quadrilateral with opposite sides that are parallel.
