parallelogram noun [C]. âº a âflat âshape that has four âsides. The two sets of âopposite âsides are âparallel and of âequal âlength to each other. (Definition of parallelogram from the Cambridge Advanced Learners Dictionary & Thesaurus Â© Cambridge University Press).
By comparison, a quadrilateral with just one pair of parallel sides is a trapezoid in American English or a trapezium in British English. The three-dimensional counterpart of a parallelogram is a parallelepiped. The etymology (in Greek ÏÎ±ÏÎ±Î»Î»Î·Î»-ÏÎ³ÏÎ±Î¼Î¼Î¿Î½, a shape of parallel lines) reflects the definition.
