## Parallelogram

Special cases Rectangle – A parallelogram with four angles of equal size (right angles). Rhombus – A parallelogram with four sides of equal length. Any parallelogram that is neither a rectangle nor a rhombus was traditionally called a rhomboid but this term is not used in modern mathematics. [1].

## Parallelogram

Example: A parallelogram where all angles are right angles is a rectangle! Area of a Parallelogram Example: A parallelogram has a base of 6 m and is 3 m high, what is its Area? Area = 6 m × 3 m = 18 m2 Perimeter of a Parallelogram The Perimeter is the distance around the edges.

## Parallelogram

It is a type of polygon having four sides (also called quadrilateral), where the pair of parallel sides are equal in length. The Sum of adjacent angles of a parallelogram is equal to 180 degrees. In geometry, you must have learned about many 2D shapes and sizes such as circles, squares, rectangles, rhombus, etc.

## What is a Parallelogram? (Definition & Properties)

Types Properties How to prove a parallelogram Parallelogram definition A parallelogram is a flat shape with four straight, connected sides so that opposite sides are congruent and parallel. This means a parallelogram is a plane figure, a closed shape, and a quadrilateral.

## Parallelogram Calculator

And, a parallelogram whose angles are all right angels and whose sides are all equal is called a square. A rhombus (or diamond) is a parallelogram with all 4 sides equal length. Units: Note that units of length are shown for convenience. They do not affect the calculations.
