Does the ordered pair express an angle in the standard position?
The ordered pair represents an angle with an initial side of , a terminal side of , and a vertex of . An angle is in standard position in a rectangular coordinate system if its vertex is the origin of the
rectangular coordinate system, and its initial side lies on the positive part of the -axis. The initial side, or , of the angle
represented by does lie on the positive part of the -axis, but the angle's vertex, , is not the origin. Therefore, the angle is
not in standard position.
