Triangle Calculator – Fast and Accurate Results

This tool lets you calculate the area and perimeter of a triangle easily.

How To Use The Triangle Calculator

Welcome to the triangle calculator! This tool can be used to compute various properties of a triangle, including sides, angles, and area based on the input values.

Steps to Use the Calculator:

Enter the values for the sides (a, b, c) and/or angles (A, B, C).
Click on the “Calculate” button to compute the results.
The results will be displayed in the results area below the input fields.

Explanation

This calculator uses basic trigonometric properties and the law of sines to calculate the unknown parameters of a triangle. Here’s how it works:

If at least two sides and an angle are provided, the calculator will compute the remaining angles.
If three sides are provided, the area of the triangle is calculated using Heron’s formula.

Limitations

This calculator assumes that valid triangle constraints are met. For example, the sum of any two side lengths must be greater than the length of the remaining side, and the sum of the angles must be 180 degrees.
