One pair.
A trapezoid is a quadrilateral with one pair of sides parallel.
A rectangle, by definition is an irregular quadrilateral. It has two pairs of parallel sides.
A square has two pairs of parallel sides.It has two pairs of parallel sides.
A quadrilateral is any figure with 4 sides. ("quad" = 4, "latus" = side). It doesn't have to have any parallel lines. If it happens to have two sides that are parallel, then it's a trapezoid. If it happens to have two pairs of parallel sides, then it's a parallelogram. Common parallelograms are rectangles, squares, and kites.
A quadrilateral has 4 sides, 2 in which never intersect. Therefore, the lines that don't intersect are called parallel. There are 4 parallel sides but has 2 pairs of parallel sides.

There are many different ways but a defining characteristic is that is has two pairs of parallel sides.

If it happens to have two pairs of parallel sides, then it's a parallelogram. Common parallelograms are rectangles, squares, and kites.
Many different quadrilaterals can have those angles. Depending upon the lengths of the sides, where the angles are and how many pairs of parallel sides it has, it could be: A cyclic quadrilateral, a trapezium, a parallelogram or a rhombus.
A parallelogram has two pairs of parallel sides.
It has 2 pairs of parallel sides
one
If it has 2 pairs of parallel lines it is a parallelogram, if it is a quadrilateral. If there is not restrictions on the number of sides, then there are many answers
