Triangle Area

The Triangle Area Calculator helps you calculate the area of a triangle based on the given side lengths or angles. It is a useful tool for various applications such as geometry, engineering, and architecture.


The most common ways to calculate the triangle area are using the base and height, SSS (side-side-side), SAS (side-angle-side), SSA (side-side-angle), ASA (angle-side-angle), or AAS (angle-angle-side) methods. The method you choose depends on which side lengths or angles you know.

To use the calculator, you have multiple options:


  • Calculate area from base and height: Enter the base and height of the triangle to determine its area. The calculator will use the formula: area = 1/2 * base * height.

  • Calculate area from side lengths (SSS method): Enter the lengths of all three sides of the triangle to calculate its area. The calculator will use Heron's formula to find the area.

  • Calculate area from side lengths and included angle (SAS method): Enter two side lengths and the included angle to calculate the area of the triangle. The calculator will use the formula: area = 1/2 * side1 * side2 * sin(angle)

  • Calculate area from two side lengths and non-included angle (SSA method): Enter two side lengths and the non-included angle to calculate the area of the triangle. The calculator will use the Law of Sines and the formula for the area of a triangle given two sides and the non-included angle.

  • Calculate area from two angles and included side (ASA method): Enter two angles and the included side length to calculate the area of the triangle. The calculator will use the Law of Sines and the formula for the area of a triangle given two angles and the included side.

  • Calculate area from two angles and non-included side (AAS method): Enter two angles and the non-included side length to calculate the area of the triangle. The calculator will use the Law of Sines and the formula for the area of a triangle given two angles and the non-included side.

Please ensure that you enter the values accurately and consistently in the respective input fields. The calculator will provide you with the area of the triangle based on the chosen calculation method.
