Scribd is the world's largest social reading and publishing site. The corners of rectangles (and squares) are also made of perpendicular line segments. There are 12 pairs of perpendicular sides. A parallelogram is a quadrilateral with 2 pairs of parallel sides. Perpendicular lines are the two distinct lines that intersect at each other at 90. If a trapeze hastwo sets of parallel sides, it is a more specific type of trapezoid called a parallelogram. A regular hexagon has all sides equal and all angles equal. For example rectangles are quadrilaterals (4-sided figures) with parallel sides, but kites are quadrilaterals with no parallel sides. Parallelograms are quadrilaterals in which opposite sides are parallel but adjacent sides are not perpendicular. It is also sometimes called a septagon, though this usage mixes a Latin prefix sept- (derived from septua-, meaning "seven") with the Greek suffix -gon (from gonia, meaning "angle"), and is therefore not recommended. Perpendicular lines are lines, segments, or rays that intersect to form right angles. Parallel Sides Concept & Examples | What Are Parallel Sides?
