Formula and methodology
Formula: Angle = arctan(opposite/adjacent); hypotenuse = √(opposite²+adjacent²).
The calculator uses tangent for the selected acute angle and Pythagoras for the hypotenuse.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Opposite leg — length units; minimum 1.0E-6; maximum 1000000
- Adjacent leg — length units; minimum 1.0E-6; maximum 1000000
Worked example
| Input | Value |
|---|---|
| Opposite leg | 3 |
| Adjacent leg | 4 |
Angle ≈ 36.870°; hypotenuse = 5 length units.
Assumptions and limits
- Both legs are positive and use one length unit.
- The triangle is Euclidean and right-angled.
- Bearing conventions, 3D orientation, and construction tolerances are not modeled.
