Full Answer

Formerly, the word trapezoid in British English meant a quadrilateral with no parallel sides, or what is often called an irregular quadrilateral.

Agreement as to the classification of trapezoids is not universal. Some regard only quadrilaterals with one single pair of parallel sides as trapezoids. Others regard the parallelogram, with two pairs of parallel sides, as a special type of trapezoid. This definition includes rectangles, rhombuses and squares as trapezoids as well because they are all special types of parallelogram.

  • Q:

    What is a trapezoid?

    A:

    A trapezoid is a closed two-dimensional geometric figure having four linear sides, two of which are parallel. The parallel segments are referred to as bases while the other two sides are called legs. The altitude of the trapezoid pertains to the distance that forms a 90-degree angle between the bases.
