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)
