Quadrant I
Every positive angle in quadrant I is already acute...so the reference angle is the measure of the angle itself:
Quadrant II
To find the reference angle measuring � for angle in Quadrant II, the formula is �
Quadrant III
To find the reference angle measuring � for angle in Quadrant III, the formula is �

Quadrant IV
To find the reference angle measuring � for angle in Quadrant IV, the formula is �

� => angle is in Quadrant II, it's same as �
the reference angle is � =>�

� => angle is in Quadrant II, same as �;
the reference angle is � =>�

degrees => degrees => angle is in Quadrant IV same as �

so, the reference angle is �
