Question

which quadrilateral is a trapezoid?

Explanation:

Step1: Recall trapezoid definition

A trapezoid is a quadrilateral with exactly one pair of parallel sides.

Step2: Analyze first option

In the quadrilateral with vertices A, B, C, D, sides AB and CD are marked as parallel (by the single - arrow markings), and it has a pair of right - angles. This is a trapezoid as it has one pair of parallel sides.

Step3: Analyze second option

In the quadrilateral with vertices E, F, G, H, there are no markings indicating parallel sides. So it is not a trapezoid.

Step4: Analyze third option

In the quadrilateral with vertices I, K, L, M, there are no markings indicating parallel sides. So it is not a trapezoid.

Answer:

The quadrilateral with vertices A, B, C, D is a trapezoid.
