Quadrilateral Calculator
Calculate your quadrilateral’s area and properties below.
What is a Quadrilateral?
A quadrilateral is a four-sided polygon defined by its four sides and angles between them. Common types of quadrilaterals include squares, rectangles, trapezoids, and parallelograms. The area of a quadrilateral depends on its specific shape and the measurements of its sides and angles.
This calculator uses your provided side lengths and the angle between diagonals to determine the quadrilateral’s area. It is particularly useful for irregular quadrilaterals that do not fit standard formulas.
How to Calculate the Area of a Quadrilateral
- Input the lengths of all four sides (A, B, C, and D) in the respective fields.
- Enter the diagonal angle in degrees. Ensure it is between 1 and 179.
- Click the “Calculate” button to compute the quadrilateral’s area.
- View the results, along with an explanation of how the area was calculated.
