Question

Is parallelogram a subset of trapezium​

Answer 1

Step-by-step explanation:

With four sides, a trapezoid is a quadrilateral, just as a square or rectangle or parallelogram. Unlike those forms, however, a trapezoid does not necessarily have to have parallel sides. ... A trapezium is a subset of trapezoids in which at least two sides are parallel; a parallelogram is one example of a trapezium.
