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.

Is a rectangle a quadrilateral with exactly one pair of parallel sides?
It is a quadrilateral with exactly 2 pairs of parallel sides.
What is a quadrilateral with one pair of parallel sides?
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.
If one pair of opposite sides of a quadrilateral is parallel and then the quadrilateral is a parallelogram?
Then, the opposite sides are congruent.
What is the Opposite Sides Parallel and Congruent Theorem?
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.
What quadrilateral that only has one pair of parallel sides?
a hexagon
