To find the angle measure using a protractor, you need to align the protractor’s baseline with one side of the angle and ensure the center hole (or point) of the protractor is placed at the vertex of the angle. Then, read the measurement on the protractor where the other side of the angle intersects the number scale.
For the angles you provided:
– 60° is obtained from the intersection point on the protractor.
– 75° is found in the same manner.
– 85° will also be the point on the scale where it aligns.
– 90° is the right angle you would find straight across from the vertex.
Make sure to always check if you are reading the outer or inner scale depending on the orientation of the angle. Good luck, and feel free to ask for more detailed assistance on any of these steps if needed!
