2. Protractor
Center Hole

3. Protractor
Straight Edge

4. Protractor
Curved Edge

5. Place the center hole over the vertex of the angle
Step 1:
Place the center hole over the vertex of the angle

6. Line up (make parallel) the straight edge with one side of the angle
Step 2:
Line up (make parallel) the straight edge with one side of the angle

7. Step 3:
Find the point where the second side of the angle intersects with the curved edge

8. Read the number on the protractor to find the measure of the angle
Step 4:
Read the number on the protractor to find the measure of the angle

9. Drawing Angles with a Protractor

10. Draw a ray with the straight edge of the protractor
Step 1:
Draw a ray with the straight edge of the protractor

11. Place the center hole over the starting point of the ray
Step 2:
Place the center hole over the starting point of the ray

12. Place a dot at the angle measure required
Step 3:
Place a dot at the angle measure required

13. Step 3:
Line up the straight edge over the starting point of the ray and the dot

14. Step 4:
Draw a ray connecting the two marks. The point at which they meet is called the vertex

15. Draw an angle which measures 120o
