Question

How are a parallelogram and a trapezoid different A a trapezoid has only one pair of parallel sides but a parallelogram has two B a parallelogram has four right angles but a trapezoid doesn't need to have four right angles C a parallelogram has only one pair of parallel sides but a trapezoid has two D a trapezoid has four right angles but a parallelogram doesn't need to have four right angles

Answer 1

The correct answer is A: A trapezoid has only one pair of parallel sides, but a parallelogram has two.

To elaborate:

- A **parallelogram** is defined as a quadrilateral with two pairs of parallel sides.
- A **trapezoid** (in some definitions, particularly in the U.S.) is defined as a quadrilateral with at least one pair of parallel sides, which means it has only one pair of parallel sides.

The other options are incorrect in their statements about the properties of these shapes.
