In mathematics there is

**determination of rectangular trapezoid**, which over is brought and in Wikipedia:

**the rectangular is name a trapezoid at which even one corner of line**. This classic determination of

**rectangular trapezoid**, bluntly rewritten from sacred mathematical books. In Euclidean geometry a

**rectangular trapezoid**always has two lines of corner, as two sides

**trapezoids**, called grounds, are parallel. Segment

**BC**, formative a direct corner with founding of

**АВ**, will be always perpendicular to the second founding of

**CD**. With one or three direct corners there can be only a curvilinear

**rectangular trapezoid**, and it is quite another other class of geometrical figures already.
