A trapezoid has only one pair of parallel sides
The name of the four-sided shape that has only one pair of parallel sides is known as a trapezoid. The other two sides are not parallel to each other. There are many other shapes with more than four sides that have one pair of parallel sides but these typically don't have special names. So assuming the question is only referring to four-sided figures, the answer is a trapezoid.
A trapezoid has only one pair of parallel sides of different lengths.
