What is the difference parallelograms and trapezoids?

Trapezoids are considered isosceles trapezoids if the legs are equal in length and both angles coming from the bases are equal. In the United Kingdom, a trapezoid is called a trapezium. In the United States, a trapezium is defined as a quadrilateral with no parallel sides, whereas the United Kingdom uses this definition for a trapezoid. read more

Trapezoids have one pair of parallel sides and parallelograms have two pars of parallel sides. If your text uses the at least one pair definition, then all parallelograms are trapezoids, and some trapezoids are parallelograms. read more

Parallelogram vs Trapezoid Parallelogram and trapezoid (or trapezium) are two convex quadrilaterals. Even though these are quadrangles, the geometry of the trapezoid differs significantly from the parallelograms. read more
