Using the information on the protractor, explain how to determine the measurement of the angle.
To determine the measurement of an angle using a protractor, follow the steps below:
1. Place the protractor on a flat surface or line, ensuring that one of its arms lies along the baseline of the angle you want to measure.
2. Identify the vertex of the angle, which is the point where the two sides of the angle intersect. It should coincide with the midpoint of the protractor.
3. Locate the scale on the protractor labeled in degrees. The scale usually starts from 0 degrees on one side and continues up to 180 degrees on the other side.
4. Observe the position of the arm opposite to the baseline, known as the rotating arm. This arm will indicate the measurement of the angle.
5. Read the scale where the rotating arm intersects it. The number on the scale closest to the arm represents the measurement of the angle in degrees.
6. If the scale is not long enough or the angle is larger than the scale allows, you may need to estimate the measurement. In this case, divide the angle into smaller parts that can be measured accurately using the protractor's scale. Add these measurements together to get the total angle measurement.
