More Practice with the Protractor
Instructions
Step 1. Practice with the Protractor
The protractor has two points labeled: a red point and a blue point.
Use the MOVE (pointer) tool 
to experiment with the two points and learn what they do.
Step 2. Measure Angles
Click on the check boxes to show one angle at a time.
Use the protractor to measure and enter the degrees in angles column in a Report Table you create on a piece of paper.
When you have finished with an angle, be sure to click again to remove it from the screen.

Step 3. Check Your Measurements
After you have measured all nine angles, click on the FINISHED check-box to see the actual measurements. If your measurement was correct, enter a check mark (√) in the Check column. If your measurement was not correct, enter the correct number of degrees then go back to that angle to see where you made your error.
