They are opposite each other as for example a rectangle has 2 pairs of parallel lines.
A diamond has two pairs of parallel lines.
NO!!!! Parallelogram : Two pairs of parallel lines ; The each pair of parallel lines is the same length. Trapezium ; One pair of parallel lines, that are not the same length. The other two sides can be the same length , but not parallel. Both figures/shapes are quadrilaterals.
A nonagon is a nine-sided polygon. In a nonagon, there are four pairs of parallel lines. This is because the nonagon can be divided into three sets of parallel lines, each containing three parallel lines. Each set of parallel lines consists of three pairs of parallel lines.
A rhombus has 2 pairs of parallel lines.
A hexagon generally has 3 pairs of parallel lines.
A regular dodecagon has six pairs of parallel lines.
it has 2 pairs of parallel lines
A trapezoid does not has 2 pairs of parallel lines. A parallelogram does.
Here are three shapes that have two pairs of parallel lines: square parallelogram rectangle There are many polygons with at least two pairs of parallel lines. hexagon (has 3 pairs of parallel lines) octagon (has 4 pairs) decagon (has 5 pairs)
A triangle has no parallel lines
A regular octagon has four pairs of parallel lines.
