A quadrilateral that is not a parallelogram (two sets of parallel sides) may be a trapezoid or a trapezium (US terms). To draw a trapezium (irregular quadrilateral), draw two parallel lines and connect them with unequal lines at non-congruent angles. If you make the angles opposite and congruent, you have drawn a trapezoid, which looks like a small stepstool with a top smaller than the base. If you make the connecting lines of equal length, you have drawn a trapezoid or parallelogram.
A quadrilateral with one pair of parallel sides is called a trapezium (most of the world) or trapezoid (US) . If it was to have two pairs of parallel sides it would be a parallelogram.
Then, the opposite sides are congruent.
The Opposite Sides Parallel and Congruent Theorem states that if a quadrilateral has a pair of opposite sides that are parallel and congruent, then the quadrilateral is a parallelogram.
That is a trapezoid.

A quadrilateral that has only one pair of parallel sides (the other pair not parallel) is a trapezium.
draw a square then tilt one line from each pair of parallel sides away from its pair then adjust the lengths of the top and bottom sides to make it match
Trapezoid
A quadrilateral has four sides that may or may not be equal or parallel If two sides are parallel and the other sides equal but not parallel it is a trapezoid
A trapezium.
One pair? If it is one pair of parallel sides, then it is a trapezoid. If it has 2 pairs of parallel sides, then it is a parallelogram.
RHOMBOID
It is not possible because a trapezoid has only 1 pair of parallel sides whereas a rectangle has 2 pairs of parallel sides
trapezoidA trapezoid has one pair of parallel sides.
A trapezium.
A kite, for example. But the general quadrilateral, with no specific name, also has no parallel sides.
