Find the length of sides or magnitude of angles using our triangle length calculator.

This free triangle calculator computes the edges, angles, area, height, perimeter, median, as well as other values and a diagram of the resulting triangle.

Jun 23, 2025 · This guide will empower you to calculate the unknown sides and angles of any triangle, whether it’s a simple right-angled shape or a more complex non-right triangle.

Use our right triangle calculator to find each side, angle, area, perimeter, height, inradius, and circumradius of a right triangle.

A triangle calculator is a tool that helps compute various properties and measurements of triangles. It can calculate side lengths, angles, area, perimeter, and other geometric characteristics based on …

The triangle calculator finds all triangle measurements – side lengths, triangle angles, area, perimeter, semiperimeter, heights, medians, inradius, and circumradius.

Enter any valid input (3 side lengths, 2 sides and an angle or 2 angle and a 1 side) and our calculator will do the rest.

Calculating the length of a triangle involves determining the length of its sides. In this article, we will explore different methods to help you find the length of a triangle’s sides with ease.

When the triangle has a right angle, then use it, that is usually much simpler. When two angles are known, work out the third using Angles of a Triangle Add to 180°. Try The Law of Sines before the …

Our Triangle Calculator helps you quickly find missing sides, angles, height, and area for any triangle type—whether it’s a right triangle, equilateral, or scalene.
