Reference Angles have to be between 0° and 90°. First, find which quadrant the angle is in. Next, determine whether the sign is positive or negative in that quadrant. Last, subtract 180° until the angle is between 0° and 90°.
Moving To Different Quadrants:
I to II/II to III/III to IV= make negative and add 180°
I to III = add 180°
I to IV = make negative and add 360°
II to IV = add 180°
