Is a quadrilateral in which opposite sides are parallel?
A parallelogram is a quadrilateral in which each pair of opposite sides is parallel.
What parallelogram has opposite sides parallel?
Rectangles
A parallelogram has opposite sides parallel and equal in length. Also opposite angles are equal (angles “A” are the same, and angles “B” are the same). NOTE: Squares, Rectangles and Rhombuses are all Parallelograms!
Are parallelogram sides parallel?
A parallelogram is a quadrilateral whose opposite sides are parallel. The opposite angles of a parallelogram are equal. The opposite sides of a parallelogram are equal.
Is it true that a quadrilateral is a parallelogram if both pairs of opposite sides are congruent?
If both pairs of opposite angles of a quadrilateral are congruent, then the quadrilateral is a parallelogram. If the diagonals of a quadrilateral bisect each other, then the quadrilateral is a parallelogram.
What is special parallelogram?

Yes. A parallelogram is a quadrilateral with 2 pairs of parallel sides. The opposite sides on every square are parallel, so every square is a parallelogram.
What is the formula for a quadrilateral?
The formula for an irregular quadrilateral — which is a polygon that has four sides that are of unequal length — is the same as that of a trapezoid. The formula is a + b + c+ d = perimeter. For example, suppose that a quadrilateral has sides with lengths of 1, 5, 3 and 4 inches.
