Is this quadrilateral a trapezoid?

yes

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

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

To see if the quadrilateral is a trapezoid, look at its opposite sides. See if they are parallel.

A quadrilateral has two pairs of opposite sides.

Imagine lines placed along the first pair of sides.

The lines cross. So, these sides are not

parallel.

Now imagine lines placed along the second pair of sides.

These lines also cross. So, these sides are not parallel either.

The quadrilateral has no pairs of parallel sides. So, it is not a

trapezoid.
