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.
A rectangle, by definition is an irregular quadrilateral. It has two pairs of parallel sides.
Infinitely many. Every regular polygon with 2n sides has n pairs of parallel sides. Then there are irregular polygons which can have parallel sides. And there are also irregular shapes which have 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.
the same as a regular quadrilateral, 4
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 trapezoid is a quadrilateral with a set of parallel lines. Because it is a quadrilateral, it has four angles.
A regular pentagon has no parallel lines, but you can create an irregular pentagon with one pair of parallel lines if you make a traditional 'house' shape with parallel 'walls'.

A trapezoid is a four sided quadrilateral that has only one pair of opposite parallel lines of different lengths.
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.
regular pentagons have no parrallel lines. irregular pentagons might but it depends. :))
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
A regular decagon will have 5 pairs of parallel sides, however, irregular decagons can have no parallel sides.
