About the Right Triangle Calculator

Given one leg and the hypotenuse of a right triangle, the Pythagorean theorem finds the other leg, and inverse sine finds the angle opposite the known leg. The known leg, hypotenuse and other leg each have their own unit selector, so you can mix units freely and the calculator converts everything automatically.

Formula: other leg = √(hyp² − leg²) · angle = arcsin(leg ÷ hyp)
