Angles are measured in degrees (°) using a protractor.
What Measures Angles?
Angles are measured in degrees, with a full circle being 360 degrees. There are also radians and gradians, but degrees are the most commonly used.
There are 360 degrees in a circle, 180 in a half–circle, 90 in a quarter–circle, and so on. To measure an angle, you need a protractor.
Place the midpoint of the protractor on the vertex of the angle, making sure that the baseline of the protractor is parallel to one of the sides of the angle.
Then, read the degree measurement where the other side of the angle crosses the baseline. There are a few things to keep in mind when measuring angles.
First, make sure that the protractor is placed so that the baseline is parallel to one of the sides of the angle. If it‘s not, the measurement will be inaccurate.
Second, be careful to read the degree measurement at the point where the other side of the angle crosses the baseline – if you read it at the wrong point, the measurement will be off by a few degrees.
Angles can be measured in either the clockwise or counterclockwise direction, but it‘s important to be consistent in the direction you choose. Otherwise, you‘ll end up with a lot of
