If we have a parallelogram where all sides are congruent then we have what is called a rhombus. The properties of parallelograms can be applied on rhombi. If we have a quadrilateral where one pair and only one pair of sides are parallel then we have what is called a trapezoid.
A parallelogram has opposite sides equal in length and parallel. A trapezoid has at least 1 pair of parallel sides.
