# How To Find Measure Of A Angle

Measuring an angle can require simple mathematical equations or more complex geometry. To measure an angle, you need a protractor. In the measurement, you will be dealing with the vertex of the angle, which is where the two lines meet to form the angle. Angles are measured in degrees.

### Step 1

Place the center of the protractor on the vertex of the angle. The center of the protractor is usually designated by a plus sign.

### Step 2

Align the protractor so one line is parallel with the bottom of the protractor. That will align one line of the angle with the plus sign on the protractor.

### Step 3

Find the measurement at which the other line of the angle bisects the half-moon part of the protractor. That number is the degree of the angle.
