## Quick Answer

Solve right triangles instantly. Enter any two known sides or one side and an angle to calculate all remaining dimensions, angles, and area.

## Definition

A right triangle calculator is a trigonometric tool that solves for missing angles, side lengths, area, and perimeter of a right-angled triangle. By utilizing the Pythagorean theorem and basic trigonometric ratios (sine, cosine, tangent), the calculator determines all properties of the triangle when any two dimensions (with at least one side) are provided. It displays step-by-step derivations for each value, helping students learn trigonometry and assisting carpenters in measuring angular cuts.

## How to Use

1. **Enter two known values** — Input any two known values, ensuring at least one is a side length.
2. **Read computed dimensions** — View the calculated lengths of the hypotenuse, legs, and internal angles.
3. **Review area and perimeter** — Review the total area and boundary perimeter with the mathematical formulas used.
