## Calculation Formula

The calculation formula for a 30 60 90 triangle is simpler than you might think. If ‘c’ is the length of the hypotenuse, the other two sides will be ‘c/2’ and ‘c*(sqrt(3))/2’.

```
Side1 = Hypotenuse / 2
Side2 = Hypotenuse * (sqrt(3)) / 2
```

## Categories of 30 60 90 Triangle Calculations
