Right Triangle accuracy and testing
This page documents how Calwarden builds trust for this calculator: source notes, regression-style default tests, limitations, assumptions, unit handling, rounding, and visible change history.
Formula source
- **Pythagorean Theorem:** a² + b² = c². **Area:** (a × b) / 2. **Angles:** Calculated using inverse tangent (arctan).
Test cases
Default input regression check
Generated from the checked-in default inputs and calculate function.
Inputs
- Side A (Leg): 3
- Side B (Leg): 4
Expected outputs
- Hypotenuse (c): 5
- Area: 6
- Angle A: 36.9 deg
- Angle B: 53.1 deg
Known limitations
- This page documents the checked-in calculator logic and does not certify results for every real-world edge case.
- Use the result as a planning estimate unless the calculator page states a stricter purpose.
Assumptions
- Both inputs are the perpendicular legs of a right triangle, not a leg and hypotenuse.
- Leg lengths are treated as positive measurements in the same unit.
- Angles are reported in degrees and rounded for display.
Unit handling
- Side A (Leg) accepts numeric values.
- Side B (Leg) accepts numeric values.
- Angle A is displayed in deg.
- Angle B is displayed in deg.
Rounding rules
- Number displays use up to 2 decimal places in the calculator UI.
