NBCT Mathematics Adolescence And Young Adulthood (AYA) Component 1 Practice Test

A trapezoid is which of the following?

A quadrilateral A triangle A pentagon A circle

Correct Answer:

A quadrilateral

Explanation:

A trapezoid is a four‑sided polygon, which means it is a quadrilateral. That makes it fit the definition of a quadrilateral, since it has exactly four sides. The other options describe shapes with a different number of sides: three for a triangle, five for a pentagon, and a circle has no sides at all. So the best description is that a trapezoid is a quadrilateral. If you’ve learned that a trapezoid typically has a pair of parallel sides, that property sits inside the broader idea that it’s a four‑sided figure.
