Right Triangle Solver
Find the hypotenuse of a right triangle using trigonometry
About this calculator
The Right Triangle Solver is a powerful trigonometry calculator that helps you find missing sides and angles in right triangles. Whether you're a student learning geometry, an engineer working on construction projects, or anyone needing quick triangle calculations, this tool uses the Pythagorean theorem and trigonometric functions (sine, cosine, tangent) to solve for unknown values. Simply input any two known measurements, and the calculator instantly determines all remaining sides and angles, making complex trigonometry problems simple and accurate.
How to use
Enter any two known values from your right triangle - this could be two sides, one side and one angle, or the hypotenuse and another measurement. Select the appropriate input fields and enter your measurements. Click calculate to instantly receive all missing sides and angles, including the hypotenuse length using precise trigonometric calculations.
Frequently asked questions
What information do I need to solve a right triangle?
You need any two measurements from the triangle - either two sides, one side and one angle, or combinations involving the hypotenuse.
Can this calculator work with different units?
Yes, the calculator works with any unit of measurement (inches, feet, meters, etc.) as long as you use consistent units throughout.
What's the difference between finding hypotenuse and other sides?
The hypotenuse is always the longest side opposite the right angle, while other sides are found using different trigonometric ratios.
