# Measuring angles review

Review measuring angles with a protractor, then try some practice problems.

## Measuring angles

Angles are measured in degrees. We can use a protractor to measure how many degrees an angle is.
Example:
Measure the following angle in degrees:
An angle is drawn that is smaller than a right angle.
First, we line up the dot on the center of the protractor with the vertex of the angle.
An angle is drawn that is smaller than a right angle. The angle is placed on top of a protractor. One ray points to 90 and the other points to 160 degrees, moving clockwise.
Next, we rotate the protractor so that the 0, degrees mark lines up with one side of the angle.
An angle is drawn that is smaller than a right angle. The angle is placed on top of a protractor. One ray points to 0 and the other points to 70 degrees, moving clockwise.
Finally, we read the protractor to see where the other side lines up.
The angle is 70, degrees.
