प्रश्न
The terminal is in II (second ) quadrant. what is the possible measure of an angle?
उत्तर
The terminal arm is in II quadrant.
If the initial arm rotates in an anticlockwise direction, the angle lies between 90° and 180°.
If the initial arm rotates in a clockwise direction, the angle lies between - 270° and -180°.
∴ the possible angles lie between 90° and 180° or -270° and -180°.
