The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure. [ There are many ways to approach the problem. The interior angle at each vertex of a regular octagon is 135. This means that the area of a parallelogram is the same as that of a rectangle with the same base and height: The base height area formula can also be derived using the figure to the right. Further formulas are specific to parallelograms: A parallelogram with base b and height h can be divided into a trapezoid and a right triangle, and rearranged into a rectangle, as shown in the figure to the left.
