A quadrilateral is a shape with four sides. A parallelogram is a quadrilateral that has two pairs of parallel sides (i.e. the sides opposite each other are parallel). A rectangle, for example, is a parallelogram. A trapezoid, however, is an example of a quadrilateral that is not a parallelogram - it has four sides, but only two of them are parallel to each other.
C. Both pairs of opposite sides are congruent and parallel.
A four-sided shape is a quadrilateral. With only one pair of parallel sides, it would be called a trapezoid (UK trapezium).
A quadrilateral (four-sided shape) is a parallelogram if it has two sets of parallel sides. If it has only one set, it is a trapezoid, also known as a trapezium.
Well that's easy. A parallelogram has two pairs of OPPOSITE SIDES. A trapezoid only has one pair of parallel sides.
I would be seriously concerned if a quadrilateral had more than two pairs of opposite sides parallel! A quadrilateral with two pairs of opposite sides parallel is a parallelogram.
Only if it is a trapezoid (US usage) with one set of parallel sides, or a parallelogram with both sets of opposite sides parallel. The term quadrilateral only means that the shape has 4 sides.
No. The only conditions to quality as a parallelogram is that it is a quadrilateral, and that opposite sides are parallel.
A trapezoid.
The trapezoid (UK trapezium) has only 1 pair of unequal parallel sides.
A quadrilateral having only one pair of parallel sides is called a trapezoid (UK trapezium).A quadrilateral having two pair of parallel sides is a parallelogram (a square, a rectangle, a rhombus, or a two-dimensional rhomboid).

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.
A trapezoid is a 4 sided quadrilateral that has only 1 pair of opposite parallel sides of different lengths.
square
It is a trapezoid which is also known as a trapezium
The quadrilateral with 1 pair of opposite sides parallel is called a trapezoid.
