Which Shape Has Two Pairs of Parallel Sides?
A parallelogram is a shape that has two pairs of parallel sides. There are three different types of parallelograms: rhombus, square and rectangle.
Parallel lines are two lines that run next to each other, an equal distance apart for the entire length of the line. A parallelogram is composed of parallel line segments. It is a type of polygon and is also considered to be a type of quadrilateral.
A polygon is defined as a two-dimensional shape that has straight sides. A quadrilateral is a type of polygon that has four straight sides and four angles. When the sides are parallel, the shape is categorized as a parallelogram.
A rhombus is a parallelogram that has four equal sides and resembles a rectangle. However, a rhombus does not have to have four right angles as does a square or rectangle. A square is a parallelogram with four sides of equal length and four right angles. It is also a type of rectangle. The third type of parallelogram is a rectangle. This shape is defined as having two pairs of parallel sides and four right angles. The sides in a rectangle, however, are not all the same length as in a square. One pair of sides in a rectangle is shorter or longer than the other.
