Trapezoids make up the set of quadrilaterals with 2 pairs of parallel sides.

In North American usage, a trapezoid is a four-sided figure with two parallel sides. Outside of North America, the same figure is called a trapezium. In general usage, the name is applied only to figures that have exactly two parallel sides. Figures that have two pairs of parallel sides are called by their more-specific name, e.g. parallelogram, rectangle, etc. depending on their angles and side lengths.
There is no generic name. Any polygon with 4 or more sides can have 2 parallel sides. There are also non-polygonal shapes that can have parallel sides: for example, a circle that is stretched out into a cigar shape can have two parallel sides.
It is called a parallelogram.
There are lots of different quadrilaterals that do not have two pairs of parallel sides: a kite, arrowhead, trapezium, and a shape which has no specific name.
The quadrilateral with two pairs of parallel sides
Parallelogram -- 2 pairs of parallel sides Trapezoid -- exactly 1 pair of parallel sides Rhombus -- 4 congruent sides Rectangle -- 4 angles congruent Square -- four angles and sides congruent
Parallelogram -- 2 pairs of parallel sides Trapezoid -- exactly 1 pair of parallel sides Rhombus -- 4 congruent sides Rectangle -- 4 angles congruent Square -- four angles and sides congruent
It is a shape which has two pairs of PARALLEL sides. Parallel sides - parallelogram. Get it?

A rectangle or a square are sets of quadrilaterals with two pairs of right angles. They each have two pairs of right angles and two sets of equal sides.
