1. Section 6.1 Notes Special Angles of the Unit Circle in degrees and radians

2. What are the special right triangles?

4. The same angles that form the angles of special right triangles are the special angles of the unit circle.

5. Let’s take a look at those beginning with the multiples of 90 o angles, also called the quadrantal angles.

6. quadrantal

7. Multiples of 45 o

10. multiples of 45 o

11. Multiples of 60 o

14. multiples of 60 o

15. Multiples of 30 o

19. multiples of 30 o
