A rectangle, by definition is an irregular quadrilateral. It has two pairs of parallel sides.
That depends on witch quadrilateral your talking about.
A diamond has two pairs of parallel lines.
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 parallelogram has 2 pairs of parallel lines
one
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.
