Question

select all the parallelograms.

Explanation:

Step1: Recall parallelogram definition

A parallelogram has two pairs of parallel - sides.

Step2: Analyze top - left shape

It has two pairs of parallel sides, so it is a parallelogram.

Step3: Analyze top - right shape

It has two pairs of parallel sides, so it is a parallelogram.

Step4: Analyze bottom - left shape

It has only one pair of parallel sides (a trapezoid), so it is not a parallelogram.

Step5: Analyze bottom - right shape

It has two pairs of parallel sides (a rectangle, which is a special parallelogram), so it is a parallelogram.

Answer:

The top - left, top - right, and bottom - right shapes are parallelograms.
