1. Measuring and Drawing Angles with a Protractor

2. Protractor Center Hole

3. Protractor Straight Edge

4. Protractor Curved Edge

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

6. Step 2: Line up the mark next to the center whole with the one side of the angle.

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

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

9. Drawing Angles with a Protractor

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

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

12. 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. Try this: Draw an angle which measures 120 o
