1. Chapter 4-1 Radian and Degree Measure Advanced Math Notes Date:_______________

2. Angles: + angles - angles

3. Standard Position for Angles:

4. Coterminal Angles: 2 angles with the same intitial and terminal sides.

5. Greek Symbols used for angles: Alpha Beta Theta As well as uppercase A,B,C.

6. Radian Measure: 1 radian = measure of a central angle (θ), that intercepts an arc (s) = to the radius (r) of the circle.

7. Circumference of a circle:

8. Sketching and finding “coterminal” angles: Add or subtract 2  from angle 1.13  3. -2  6 3 2.3  4

9. Complementary and Supplementary angles: ComplementarySupplementary

10. Examples: if possible, find the complement and supplement of the angles. A. 2  5 B.4  5
