Formula and methodology
Formula: c = √(a²+b²); area = ab/2; perimeter = a+b+c; angle A = atan(a/b).
The Pythagorean theorem gives the side opposite the right angle. The same two perpendicular legs determine area, perimeter, and the acute angle adjacent to leg b.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Leg a — units; minimum 1.0E-6; maximum 1000000000
- Leg b — units; minimum 1.0E-6; maximum 1000000000
Worked example
| Input | Value |
|---|---|
| Leg a | 3 |
| Leg b | 4 |
Hypotenuse: 5 units; area: 6 square units; angle A: 36.87°.
Assumptions and limits
- The two inputs are perpendicular legs of a Euclidean right triangle.
- All lengths use one unit and the area uses squared units.
- The reported angle is in degrees and is measured from leg b toward the hypotenuse.
