The more common definition of a trapezoid (or trapezium, outside of North America) is a four-sided figure with exactly one pair of parallel sides. By this definition, figures with two sets of parallel sides such as a rectangle are nottrapezoids.
Some mathematicians use a more general definition that allows for one or more pair of parallel sides. By this definition, a rectangle, square, or rhombus would be considered as special cases of a trapezoid.

One pair.
2It has one pair more because a parallelogram has two pairs of parallel sides whereas a trapezoid only has one pair of opposite parallel sides of different lengths.
A trapezoid has one pair of parallel sides. They are opposite parallel lines of different lengths.
A trapezoid or trapezium has four sides, two of which are parallel.
A trapezoid has only one pair of parallel sides. These parallel sides are opposite and are of different lengths.
