Using the information on the protractor, explain how to determine the measurement of the angle. What is the measure of the angle?
(In the image, the vertex of the angle has been aligned with midpoint of the straight edge of the protractor, one leg straight edge of the protractor, and one leg of the angle lies between 160/20 and 150/30. The second leg of the angle intersects the protractor between 130/50 to 140/40)
To determine the measurement of the angle using the protractor, follow these steps:
1. Place the protractor on a flat surface with the midpoint of its straight edge aligned with the vertex of the angle.
2. Look at the scale on the protractor. It is divided into degrees from 0 to 180, with the numbers increasing in a counterclockwise direction.
3. Find the leg of the angle that lies between 160/20 and 150/30. This means the angle is between 150 degrees and 160 degrees.
4. Next, find the leg of the angle that intersects the protractor between 130/50 and 140/40. This means the angle is between 130 degrees and 140 degrees.
5. The measure of the angle is the value that falls within the range of both legs. In this case, the measure of the angle would be between 130 degrees and 140 degrees. The exact measurement cannot be determined without a more precise scale on the protractor or a clearer indication of where the legs intersect the scale.
