How to use a protractor to find an angle?
Understand the Problem
The question is asking for a step-by-step guide on how to use a protractor to measure an angle. This involves placing the protractor correctly, aligning it with the angle, and reading the measurement from the scale.
Answer
Position vertex at center, align one side with 0 degrees, and read the measurement.
To measure an angle using a protractor, position the vertex at the center, align one side with the 0-degree line, and read the measurement where the other side crosses the scale.

More Information
Protractors are tools used in geometry to measure angles, often where two lines meet. They are commonly graduated in degrees, from 0° to 180° or 0° to 360°.
Tips
Ensure the protractor is properly aligned and that you are reading the correct scale, especially when measuring angles greater than 90°.
