Short Diagonal of Parallelogram given Sides and Obtuse Angle between Sides Calculator

Calculate Short Diagonal of Parallelogram







Formula

The formula to calculate the Short Diagonal of Parallelogram given Sides and Obtuse Angle between Sides is:

\[ d_{\text{Short}} = \sqrt{e_{\text{Long}}^2 + e_{\text{Short}}^2 + (2 \cdot e_{\text{Long}} \cdot e_{\text{Short}} \cdot \cos(\angle_{\text{Obtuse}}))} \]

Definition

The Short Diagonal of a Parallelogram is the length of the line joining the pair of obtuse angle corners of a Parallelogram. The Long Edge of a Parallelogram is the length of the longest pair of parallel sides in a Parallelogram. The Short Edge of a Parallelogram is the length of the shortest pair of parallel edges in a Parallelogram. The Obtuse Angle of a Parallelogram is the measure of the pair of opposite angles which are greater than 90 degrees in a Parallelogram.

Example Calculation

Let's assume the following values:

Using the formula:

\[ d_{\text{Short}} = \sqrt{12^2 + 7^2 + (2 \cdot 12 \cdot 7 \cdot \cos(2.3561944901919))} = 8.61429397923665 \]

The Short Diagonal of the Parallelogram is 8.61429397923665 meters.
