Angle Of Right Triangle Calculator
Result
Angle Of Right Triangle Calculator The Angle of a Right Triangle Calculator finds the two acute angles and the hypotenuse of a right triangle from the lengths of its two legs. It uses the inverse tangent of the opposite over the adjacent leg, with the sec — free online calculator.
Formula
- Angle Of Right Triangle Calculator calculates its result from Opposite, Adjacent. It uses the formula angle = arctan(opposite ÷ adjacent); other angle = 90° − angle; hypotenuse = √(opposite² + adjacent²). Change any input to recalculate the result instantly.
- The main inputs are Opposite, Adjacent. Enter them in the units and format shown in the calculator.
- Keep comparable quantities in compatible units whenever the formula combines or compares them.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: Angle Of Right Triangle
- Opposite: 2
- Adjacent: 3
Using Opposite = 2, Adjacent = 3, the calculated result is 3.6055512755.
