Quadrilateral Calculator
Area Formulas:
- Square: \( \text{Area} = \text{side}^2 \)
- Rectangle: \( \text{Area} = \text{length} \times \text{width} \)
- Parallelogram: \( \text{Area} = \text{base} \times \text{height} \)
- Rhombus: \( \text{Area} = \frac{\text{diagonal}_1 \times \text{diagonal}_2}{2} \)
- Trapezoid: \( \text{Area} = \frac{(\text{base}_1 + \text{base}_2) \times \text{height}}{2} \)
- Kite: \( \text{Area} = \frac{\text{diagonal}_1 \times \text{diagonal}_2}{2} \)
- Irregular Quadrilateral: Shoelace Formula
Perimeter Formula:
\( \text{Perimeter} = \text{sum of all side lengths} \)
What Is the Quadrilateral Calculator?
The Quadrilateral Calculator is an interactive tool designed to calculate and display key geometric properties of various four-sided shapes. It supports common quadrilaterals such as squares, rectangles, rhombuses, trapezoids, kites, and even irregular quadrilaterals defined by custom coordinates.
