How the 30-60-90 Triangle Calculator Works
A 30-60-90 triangle is a right triangle with angles measuring 30°, 60°, and 90°. Its sides always follow the ratio:
- Short Leg (opposite 30°): x
- Long Leg (opposite 60°): x × √3
- Hypotenuse: 2 × x
The calculator simplifies this by requiring only the short leg as input. Using the above ratios, it calculates the long leg and hypotenuse instantly, eliminating manual calculations and minimizing errors.
