  1. The Unit Circle Co-Terminal Angles

  2. Remember • Label the following quadrants: II I IV III • When labeling, did you move clockwise or counter-clockwise? counter-clockwise

  3. Standard position • An angle that is in standard position means that the initial sideof the angle is on the positive x-axis. • Where the angle ends is said to be the terminal side.

  4. Direction • An angle can move counter-clockwise (positive). 135° is the same as -225° 135° -225° • Or clockwise (negative).

  5. Many turns • A wheel can turn many times:

  6. Practice 2. Circle the pair of coterminal angles: 240° & 600° 90° & 290° -100° & 100° 1. Sketch the following angles: 120° -195° 400° 3. Name a positive then a negative angle that is coterminal with 20°.
