One such pattern is called the square of a sum. Another is called the square of a difference. Answer Key Trigonometry Lesson One: Degrees and Radians Note: For illustrative purposes, all diagram angles will be in degrees. 120°-120° e a) The rotation angle between the initial arm and the terminal arm is called the standard position angle. Example 1: b) An angle is positive if we rotate the terminal arm counter-clockwise, and negative 4 8.3 Trigonometry Trigonometry in the Calculator Use a Calculator to find each trig value.
