Example Calculation
Scenario:
- Leg A = 6
- Leg B = 8
- Unit = meters
- Calculation type = Hypotenuse
Result:
- Hypotenuse = 10 m
- Angle A ≈ 53.13°
- Angle B ≈ 36.87°
- Area = 24 m²
- Perimeter = 24 m
- Triangle Type = Right Triangle
This makes it extremely useful for geometry homework, construction layouts, and trigonometry problems.
