Question

select all the trapezoids.

Explanation:

Step1: Recall trapezoid definition

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

Step2: Analyze each figure

• Top - left (red): Quadrilateral, check for parallel sides. Appears to have one pair of parallel sides (the two non - slanted sides? Wait, no, re - check. Wait, the red figure: let's see, the two sides that are more horizontal? Wait, actually, the blue (top - right), green (bottom - left) and red (top - left) – wait, the bottom - right is a pentagon? No, wait the bottom - right figure: it has 5 sides? No, wait no, looking at the figures:

Wait, the four figures:

1. Top - left (red): Quadrilateral, has one pair of parallel sides (the two sides that are "horizontal" in orientation, or the two sides that are parallel).
2. Top - right (blue): Quadrilateral, has one pair of parallel sides (the top and bottom bases, typical trapezoid shape).
3. Bottom - left (green): Quadrilateral, has one pair of parallel sides (the two sides that are parallel, similar to trapezoid).
4. Bottom - right (blue): This is a pentagon? No, wait no, it has 5 sides? Wait, no, looking at the figure, it's a quadrilateral? Wait, no, the bottom - right figure: let's count the sides. It has 5 sides? No, maybe I miscount. Wait, no, the bottom - right figure: it looks like a triangle with a cut, but actually, it has 5 sides? No, no, the original problem: the four figures. Wait, the bottom - right is a quadrilateral? No, maybe it's a pentagon. Wait, no, the definition of trapezoid is quadrilateral with at least one pair of parallel sides. So the top - right (blue), top - left (red), bottom - left (green) are quadrilaterals with at least one pair of parallel sides. The bottom - right: let's see, does it have parallel sides? No, because it's a non - trapezoid shape (maybe a pentagon? Wait, no, the figure: let's check again.

Wait, the top - right (blue) is a trapezoid (has two parallel sides, top and bottom). The top - left (red) is a trapezoid (has one pair of parallel sides). The bottom - left (green) is a trapezoid (has one pair of parallel sides). The bottom - right: let's see, the sides: it's a quadrilateral? No, it has 5 sides? Wait, no, the figure: maybe I made a mistake. Wait, the problem is to select all trapezoids. So the correct ones are the top - left (red), top - right (blue), and bottom - left (green). Wait, but let's confirm the definition. In some definitions, a trapezoid has exactly one pair of parallel sides, in others at least one. Assuming the "at least one" definition (more common in US), then:

• Top - left (red): Quadrilateral, one pair of parallel sides. Trapezoid.
• Top - right (blue): Quadrilateral, one pair of parallel sides (top and bottom). Trapezoid.
• Bottom - left (green): Quadrilateral, one pair of parallel sides. Trapezoid.
• Bottom - right (blue): Not a trapezoid (either not a quadrilateral or no parallel sides).

So the trapezoids are the top - left (red), top - right (blue), and bottom - left (green).

Answer:

The trapezoids are the top - left (red - colored quadrilateral), top - right (blue - colored quadrilateral), and bottom - left (green - colored quadrilateral).
