Use the protractor to measure the angle to the nearest degree.
To use the protractor to measure an angle to the nearest degree, follow these steps:
1. Place the center hole of the protractor on the vertex (corner) of the angle.
2. Make sure the zero line (or the baseline) of the protractor aligns with one side of the angle.
3. Read the measurement indicated by the other side of the angle on the protractor scale.
4. Round the measurement to the nearest degree.
For example, if the measurement falls between 60 and 61 degrees, it can be rounded to 60 degrees. If it falls between 61 and 62 degrees, it can be rounded to 61 degrees. Repeating this process will allow you to measure any angle to the nearest degree using a protractor.
