In trigonometry, angles are formed by the rotation of a ray about its endpoint from an initial position to a terminal position. The measure of an angle can be negative or positive, depending on the direction of its rotation. Which direction of rotation returns negative angles: counter-clockwise (ccw) or clockwise (cw)?
cw
