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).
I think this person means the trapazoid. It has only one pair of parallel sides.
Any shape with more than three sides can have a pair of parallel sides,but doesn't necessarily have.Every square, rectangle, rhombus, parallelogram, and trapezoid hasat least 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 4 sides, 2 acute and 2 obtuse angles, and only one pair of parallel sides
A trapezoid has only one pair of parallel sides of different lengths.
A trapezoid has only one pair of parallel sides
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 has only 1 pair of opposite parallel sides of different lengths.

A trapezoid is a four-sided figure (or "quadrilateral") with only one pair of parallel sides.
Any shape wit four of more sides can have one pair of parallel sides.
An isosceles trapezoid would seem to fit the given description.
