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.
Most quadrilaterals do not have opposite sides which are equal in length. Sadly, there is no special name for them.
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.

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.
