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.
A trapezoid.
No. The only conditions to quality as a parallelogram is that it is a quadrilateral, and that opposite sides are parallel.
The trapezoid (UK trapezium) has only 1 pair of unequal parallel sides.
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 type of quadrilateral that does not have two pairs of opposite sides that are parallel. Instead, it has only one pair of opposite sides that are parallel, while the other pair is not. This distinguishes trapezoids from parallelograms, rectangles, and squares, which do have both pairs of opposite sides parallel.

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).
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.

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