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.
A rectangle, by definition is an irregular quadrilateral. It has two pairs of parallel sides.
A trapezoid is a four sided quadrilateral that has only one pair of opposite parallel lines of different lengths.
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
That depends on witch quadrilateral your talking about.
A diamond has two pairs of parallel lines.
A rhombus has 2 pairs of parallel lines.
A regular dodecagon has six pairs of parallel lines.
it has 2 pairs of parallel lines
it has too parallel lines!
A pentagon has no parallel lines.
