Question

select all the trapezoids.

Explanation:

A trapezoid is defined as a quadrilateral with at least one pair of parallel sides.

1. The top-left figure: It has one pair of sides that are both perpendicular to a third side, so they are parallel. This is a trapezoid.
2. The top-right figure: It has one pair of sides that are both perpendicular to a third side, so they are parallel. This is a trapezoid.
3. The bottom-left figure: It has two pairs of parallel sides (a parallelogram). By definition, this is also a trapezoid (as it meets the "at least one pair" condition).
4. The bottom-right figure: It has one clearly marked pair of parallel sides. This is a trapezoid.

Answer:

All four figures are trapezoids:

1. Top-left green quadrilateral
2. Top-right blue quadrilateral
3. Bottom-left orange parallelogram
4. Bottom-right orange quadrilateral
