A trapezoid which is also called a trapezium depending where you live.
A four-sided shape is a quadrilateral. With only one pair of parallel sides, it would be called a trapezoid (UK trapezium).
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.
No. A trapezoid is a 4-sided flat shape with straight sides that has a pair of opposite sides parallel. The opposite angles not congruent.
It is not possible to have 1 parallel side since it must be parallel to another side. A four sided shape with 1 PAIR of parallel sides is a trapezium (or trapezoid).
A trapezoid is a four-sided figure with only one pair of parallel sides. A square will always have two pairs of parallel sides.
A trapezoid is a four-sided figure (or "quadrilateral") with only one pair of parallel sides.
A four-sided shape is a quadrilateral. With only one pair of parallel sides, it would be called a trapezoid (UK trapezium).
A trapezoid has a pair of parallel sides of different lengths
a square or a trapezium
A trapezoid is a 4 sided shape that has one pair of parallel sides of different lenghts
square

An irregular hexagon.
It is a closed four-sided shape with 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.
Not all four-sided shapes have one pair of parallel sides. For example, a rectangle and a trapezoid can have one pair of parallel sides, but a general quadrilateral does not necessarily have any parallel sides. Shapes like rhombuses and squares have two pairs of parallel sides, while irregular quadrilaterals may have none. Thus, the presence of parallel sides depends on the specific type of four-sided shape.
A trapezium (trapezoid).
