### Measuring and Drawing Angles with a ProtractorBy Christine BergEdited By V Hamilton

Protractor

Center Hole

Protractor

Straight Edge

Protractor

Curved Edge

Step 1:

Place the center hole over the vertex of the angle

Step 2:

Line up (make parallel) the straight edge with one side of the angle

Step 3:

Find the point where the second side of the angle intersects with the curved edge

Step 4:

Read the number on the protractor to find the measure of the angle

### Drawing Angles with a Protractor

Step 1:

Draw a ray with the straight edge of the protractor

Step 2:

Place the center hole over the starting point of the ray

Step 3:

Place a dot at the angle measure required

Step 3:

Line up the straight edge over the starting point of the ray and the dot

Step 4:

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

Try this:

Draw an angle which measures 120o
