Given: $2$ rad $=114.6^{\circ}$ The standard position of an angle occurs when we place its vertex at the origin of a coordinate system and its initial side on positive x-axis. A positive angle is obtained by rotating the initial side counterclockwise until it coincides with the terminal side. Likewise, negative angles are obtained by clockwise rotation . Since, the given angle is positive therefore, we will move counterclockwise from the x-axis as depicted in the figure:
