Question

complete the sentence below. some ____________ are trapezoids, but others are not. quadrilaterals rhombuses parallelograms squares

Explanation:

A trapezoid is a quadrilateral with one pair of parallel sides. Since a quadrilateral is a general four - sided polygon, some quadrilaterals can have one pair of parallel sides (be trapezoids) while others can have different side - parallel arrangements. Rhombuses, parallelograms, and squares have two pairs of parallel sides and thus are not trapezoids (by the non - inclusive definition of trapezoids where a trapezoid has exactly one pair of parallel sides).

Answer:

A. quadrilaterals
