## How do you find a degree of an angle?

It’s easy to use: **Align the “0” gradation on the protractor with one of the rays of the angle and position the middle circle on the protractor on the vertex of the angle**. Note where the other ray of the angle lines up on the protractor – this will give you the angle degrees.

## How do you determine the angle to cut wood?

The formula involves **dividing 360 by the number of sides to calculate the** corner angle. Then divide it by two to get the miter angle. If you’re making a five-sided project with all sides equal, you divide 360 by five to get 72 degrees. So each joint or corner forms a 72-degree angle.

## How do you find a missing side?

**How to find the sides of a right triangle**

- if leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root: a = √(c² – b²)
- if leg b is unknown, then. b = √(c² – a²)
- for hypotenuse c missing, the formula is. c = √(a² + b²)
