What is a Triangle Calculator?
A triangle calculator computes various properties of a triangle based on the lengths of its three sides. It calculates area, perimeter, angles, and determines the triangle type (equilateral, isosceles, scalene, or right triangle).
This calculator uses Heron's formula for area calculation and the Law of Cosines for angle determination. It automatically validates that the triangle is valid (sum of any two sides must be greater than the third side).
Triangle Types
Equilateral Triangle
All three sides are equal. All angles are 60°.
Isosceles Triangle
Two sides are equal. Two angles are equal.
Scalene Triangle
All three sides are different lengths.
Right Triangle
One angle is exactly 90°. Follows Pythagorean theorem.
