Lesson 5-1: Angles and Degree Measure LEQ - What are co-terminal angles and reference angles?

3
Give the angle measurements for each of the following: 3 clockwise rotations 2.4 counterclockwise rotations Positive angles are measured counter-clockwise Negative angle are measured clockwise

6
If αis the degree measure of an angle, then all angles meas°, where k is an integer, are coterminal with α. Ex. Identify all angles coterminal with 45°

7
If 775º is in standard position, Determine a coterminal angle that is between 0 and 360º. State the quadrant in which the terminal side lies. If -777º is in standard position, Determine a coterminal angle that is between 0 and 360º. State the quadrant in which the terminal side lies.

12
Convert 52.125º to degrees, minutes and seconds. Convert 87.234º to degrees, minutes and seconds. Convert 13º 5' 3“ to degrees.
