Chapter 4: Trigonometry 4.1 Radians and degree measures An angle has two sides and one vertex. An angle can be displayed in two different positions: Free position: Standard Position: Initial side In the standard position when the angle is positive its drawn counter-clockwise. When the angle is negative it means that the angle is drawn clockwise and its negative. We name angles with a Greek letter inside the angle or with an uppercase letter outside of the angle. θ A We determine the “measure of an angle” be the amount of its rotation from the initial side to the terminal side. Angle measures (Radian) “One Radian” is the measure of
