16. an angle less than 90
17. angles that share a common ray & vertex

2. a triangle with 3 equal side and 3 equal angles
3. angles that are across from each other when 2 lines intersect
4. two lines that never intersect
6. Angles that are next to each other
7. a triangle with 2 equal sides & equal angles
8. Angles that sum to 180
9. angles that are the parallel lines and on the same side of the transversal
10. an angle that sums to 90
13. represents parallel lines
14. < that are in the same position on the parallel lines in relation to the transversal
