An isosceles trapezoid
Since a trapezoid is a quadrilateral whose bases are parallel and not congruent, then one of its sides can be perpendicular to its bases (as the shortest distance between two parallel lines). Such a trapezoid is called a right trapezoid.

A trapezoid whose non-parallel sides are of different lengths.
It is a trapezoid in which the non-parallel sides are of the same length and subtend equal angles with the base. It can be viewed as an isosceles triangle whose apex has been removed by a line parallel to its base.
