rhombus

Answer 1

The quadrilateral that has one pair of parallel sides, but is not a parallelogram, is a **trapezoid**. A trapezoid has only one pair of opposite sides that are parallel, while a parallelogram has both pairs of opposite sides parallel. The other options listed (rhombus, rectangle, and square) are all types of parallelograms.
