If the 2 nonparallel sides are of equal length it is a regular trap. Otherwise it is not.
trapiziod
A trapizoid is particularly a shape in which, has precicely four sides to be exact.
Similar polygons have congruent angles and the same shape (but not necessarily the same size). Since the shape of a square and a rectangle is different from the shape of a trapezoid, they are not similar to it.
