In geometry, a trapezoid is a quadrilateral (four-sided figure) in which only one pair of opposite sides are parallel. Trapezoids are also known as trapeziums. The parallel sides of a trapezoid are called the bases. The nonparallel sides are called legs. A trapezoid, like a circle, has 3...
A trapezoid is a closed two-dimensional figure with four sides. Two parallel sides of a trapezoid are referred to as the bases of the trapezoid. The non-parallel sides of a trapezoid are referred to as the legs or lateral sides. The altitude is the shortest distance between two parallel si...
