2.  Angle- generated by rotating one of two rays that share a fixed endpoint called a vertex.  Initial side- the fixed side of the angle.  Terminal side- the rotating side of the angle.  Standard Position- an angle with it’s vertex at the origin and it’s initial side along the positive x-axis

3.  Degree- the unit used to measure angles  Minutes- the 60 equal parts of the degree subdivision  Seconds- the 60 equal parts of the Minutes subdivision

7. Las Vegas, Nevada, is located at about 36.175° north latitude. Change to 36.175° to degrees, minutes, and seconds.

8. 36.175°= 36° + (0.175  60) = 36° + 10.5’ = 61° + 10 + (0.5  60)  = 61° + 10 + 30  36.175° can be written as 60° 10 30 .

9. Las Vegas is also located at 115° 8 11  west longitude. Write 115 ° 8 11  as a decimal rounded to the nearest thousandth.

10. 115 ° 8 11”= 115° + 8 1/60 + 11  1 1/3600 about 115.136° 115 ° 8 11  can be written as 115.136°.

11. Give the angle measure represented by each rotation. 3.75 rotations clockwise

12. 3.75  (-360) = -1350 The angle measure of 3.75 clockwise rotations is -1350°

13. 4.2 rotations counterclockwise

14. 4.2  360 = 1512 The angle measure of 4.2 counterclockwise rotations is 1512°.
