1. Writing and Geometry Use symbols to express geometric ideas. Use protractors to measure angles. Created by: Jilleen Flynn

2. Use the diagram to name… A B D C E

3. two intersecting rays DE intersects CE A B D C E

4. two parallel line segments AB ll DE orBA ll ED A B D C E

5. two perpendicular lines AB BE or EB BA A B D C E

6. one angle with B as its vertex < ABE or < EBA A B D C E

7. How many points are labeled? 5 points (A, B, C, D, and E) are labeled. A B D C E

8. What tool would you use to measure that angle? a protractor Click the protractor to try some fun interactive online activities.
