That is how it is defined: parallelograms have two sides that have congruent adjacent angles, so that the remaining two sides must be parallel and equal in length.
Parallelograms include rectangles (all right angles), squares (all right angles), rhomboids, and rhombi (the latter two have congruent but non-right angles, and a rhombus has 4 equal sides).
Two pairs of opposite sides are parallel in a parallelogram
A parallelogram has two pairs of parallel sides.
Yes it does. All the four sides have an opposite. The opposites are parallel so in a parallelogram there are two pairs of parallel sides.
A parallelogram has two pairs of opposite parallel sides (for a total of four sides).
A Parallelogram has 2 pairs of opposing sides that are parallel.
A parallelogram has two pairs of opposite parallel sides
Parallelogram
A parallelogram has two pairs of parallel sides.
If by 'ides' you mean sides, then there are two pairs of parallel sides in a parallelogram.
A quadrangle (or quadrilateral) that has two pairs of parallel sides is called a parallelogram.
A parallelogram has two pairs of parallel sides.
Yes, opposite sides are parallel
