**What Is The Terminal Side Of An Angle**. In other terms it is the ray where measurement of an angle stops. The terminal side of an angle theta drawn in angle standard position is the side which isn't the initial side.

The sides of an angle refer to the two rays or line segments that form the angle.in the figure below, rays ba and bc are the sides of angle abc. The reference angle depends on the quadrant's terminal side. * for angles greater than 360, you must subtract 360(or multiple) from the angle until the result is between 0 and 360.
