A square has.
Most of the time.If a quadrilateral contains no parallel lines or two pairs of parallel lines then it is not a trapezium.

A quadrilateral with 2 pairs of parallel line segments is a parallelogram. Parallelograms include rectangles, rhombuses, and squares.
Not if the two pairs give rise to 4 parallel lines.

A quadrilateral doesn't have to have any pairs of parallel lines. It depends what kind of quadrilateral you are talking about... Rectangle- Yes (2 pairs) Square- Yes (2 pairs) Trapezoid- Yes (1 pair) Parallelogram- Yes (2 pairs) Rhombus- Yes (2 pairs)
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.

An irregular quadrilateral can have zero, one, or two pairs of parallel lines, but typically it has no parallel lines. By definition, an irregular quadrilateral does not have equal sides or angles, which means it does not conform to the properties of specific types of quadrilaterals like rectangles or parallelograms that have parallel sides. Thus, the most common scenario for an irregular quadrilateral is having no parallel lines at all.
It is called a Rhombus.
