Activity #17__ the 'Angle with Given Size' tool
Activity Goal:
Explore how to create one or more angles by using the Angle with Given Size tool. See below for directions.
Directions:
Activity #1
1. Under Line Tools, construct a ray (starting at A and passing through point B).
2. Under Measure Tools, select Angle with Size tool.
3. Click point B, and then Point A .
4. After angle box opens up, enter 70 degrees and click counterclockwise.
5. If you can't see point B' (3rd point), use the Move tool to move point B closer to A.
6. Construct another ray AB' (starting at A and passing through B' ).
7. Describe what you have constructed.
Activity #2
8. Use the undo arrow to back up steps until you just have the ray AB ( with points A and B).
9. Select Angle with Size tool.
10. Click Point B and then A.
11. Enter 70 degrees and click clockwise.
12. Construct another ray AB'
12. Explain what how angle A is different from Activity #1.
Activity #3
13. Undo your last step so that you have the ray AB.
14. Select Angle with Size tool.
15. Click Point A and then B.
16. Enter 70 degrees and counterclockwise.
17. Construct another ray BA'.
18. Explain how this new angle is different from the others .
Activity # 4
19. Same as in Activity #3 but instead of choosing counterclockwise, choose clockwise.
