A parallelogram is a quadrilateral in which both pairs of opposite sides are parallel. Its properties include:

  • Opposite angles are congruent.
  • Each diagonal divides the figure into 2 congruent triangles.
  • Both diagonals together divide the figure into 2 pairs of congruent triangles. All 4 triangles have an equal area.

Formula for the Area of a Parallelogram

The area of a parallelogram is as follows:

$A=bh$ where $A$ is the area of the parallelogram, and $b$ and $h$ are the base and height of the parallelogram, respectively.
