Parallelogram
(Jump to Area of a Parallelogram or Perimeter of a Parallelogram)
A Parallelogram is a flat shape with opposite sides parallel and equal in length.
| Opposite sides are parallel | |
Opposite sides are equal in length | |
| Opposite angles are equal (angles A are the same, and angles B are the same) | |
| Angle A and angle B add up to 180°, so they are supplementary angles. |

NOTE: Squares, Rectangles and Rhombuses are all Parallelograms!
Example:
A parallelogram where all angles are right angles is a rectangle!
Area of a Parallelogram
The Area is the base times the height: Area = b × h (h is at right angles to b) |
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.
The Perimeter is 2 times the (base + side length): Perimeter = 2(b+s) |
