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 trapezium is a shape with four sides. Of these, one pair of sides are parallel. The only restriction on the other pair is that they are not parallel (because you then have a parallelogram).
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
It is a closed four-sided shape with one pair of parallel sides.
