question

Select all the trapezoids.

key idea

A trapezoid is a quadrilateral with at least one pair of parallel sides. A quadrilateral is a four-sided shape.

Two sides of a shape are parallel if lines placed along them never cross.

Parallel

Not parallel

In a quadrilateral, parallel sides must be opposite sides. This means they do not share a vertex.

Opposite

Not opposite

solution

All the shapes are quadrilaterals. To see which ones are trapezoids, find the quadrilaterals with at least one pair of parallel sides.

For each quadrilateral, look at both pairs of opposite sides. Imagine lines placed along these sides, to see if they are parallel.

This quadrilateral has no pairs of parallel sides.

Not parallel

So, it is not a

trapezoid.

This quadrilateral has one pair of parallel sides.
