Final answer:
Parallelograms, rectangles, rhombuses, and squares all have at least one pair of parallel sides.
Step-by-step explanation:
Out of the given options, parallelograms have at least one pair of parallel sides.
Parallelograms are a type of quadrilateral that have opposite sides that are parallel. This means that there are always two pairs of sides that are parallel to each other.
Rectangles, rhombuses, and squares are all special types of parallelograms, so they also have parallel sides.
