A trapezoid is any four-sided figure that has two sides that are parallel.
Greek trapezion = a trapezium - a quadrilateral with 2 sides parallel, and eidos = shape or form, hence resembling a trapezium.
Gr. trapezodes, from trapezoin, a table or counter, eidos, resemblance. Resembling a trapezium. The trapezoid body of the pons.
A quadrilateral such that at least one set of opposite sides are parallel.
a four-sided plane closed figure with only one pair of parallel sides, called bases.
a quadrilateral with exactly one pair of parallel sides

A trapezoid is a quadrileteral (four-sided) geometric figure having two parallel sides.
A quadrilateral with one pair of parallel sides and one pair of sides that are not parallel.
A trapezoid (in North America) or trapezium (in Britain and elsewhere) is a quadrilateral two of whose sides are parallel to each other. Some authors define it as a quadrilateral having exactly one pair of parallel sides, so as to exclude parallelograms.
