5. B D E What is the difference between a point and a vertex?
Point D is listed as a vertex. Why?
In order for point B and point E to become vertices (each as a single vertex), what would need to happen?

6. Which angles appear to be the same measure?

7. Two Parallel Lines and a Transversal

9. Turn to Page S.63
Which angles Located on Line 1 appear to be the same measure?
Which angles Located on Line 2 appear to be the same measure?
Do the angles formed on Line 1 appear to be congruent or not congruent to those formed on Line 2?

10. Turn to Page S.63
Using a sheet of copy paper, trace angle 1. Through a rotation, reflection, or translation, try to match it to another numbered angle.
Using a sheet of copy paper, trace angle 2. Through a rotation, reflection, or translation, try to match it to another numbered angle.
Using a sheet of copy paper, trace the blue and red lines that form angles 1,2,3, and 4. Using a translation and rotation, try to map your traced image to angles 5,6,7, and 8.

12. What do all of these different angle relationships have in common?
All relationships show paired congruent angles.
