Quadrilaterals are two-dimensional shapes that have four sides. Quadrilaterals that have only one set of parallel sides are called trapezoids.
Trapezoids. All other quadrilaterals either have two pairs of parallel sides or none.
trapezoid
yes
Quadrilaterals that have two pairs of parallel sides include rectangles, rhombuses, and squares. These shapes are all classified as parallelograms, a category of quadrilaterals characterized by opposite sides being both equal in length and parallel. Additionally, trapezoids can also have one pair of parallel sides, but only parallelograms have two pairs.
A trapezium (trapezoid, US)
A trapezoid has one pair of parallel sides. All other quadrilaterals have no parallel sides or two pairs of parallel sides.
Trapezoids. All other quadrilaterals either have two pairs of parallel sides or none.
Trapezium
No. A trapezoid only has one pair of parallel sides. A chevron has no parallel sides.
Yes. All of them do, but the trapezoid is the only one with only one pair of parallel sides.

No. An example of a quadrilateral that doesn't have a pair of parallel sides is a kite.
A trapezium (trapezoid, US)
A trapezoid (or trapezium) does not have two pairs of parallel sides, as it has only one pair of parallel sides. Other quadrilaterals, such as a kite or an irregular quadrilateral, also lack this property. In contrast, parallelograms, rectangles, rhombuses, and squares all possess two pairs of parallel sides.
Any that are not a parallelogram (rhombus, rectangle, square). These would include all irregular quadrilaterals as well as trapezoids (trapeziums) which have only one set of parallel sides.
