Answer: A regular quadrilateral is one with equal sides and equal angles, so it is a square. To negate this definition, we say an irregular quadrilateral is one where the sides are unequal or the angles are unequal OR BOTH. In simpler terms, we could say it is a quadrilateral which is not a square.

How many parallel lines does a irregular quadrilateral have?

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.
