Question

All quadrilaterals are parallelograms

Answer 1

The statement is true on apex, just took the test so I know.

Answer 2

This statement is false. Parallelograms are four-sided figures that have two sets of parallel sides. A quadrilateral is simply a four-sided figure. The sides may be any length and at any angle from one another. So all parallelograms are quadrilaterals, but only some quadrilaterals are parallelograms.
