**is the angle formed by a terminal side of a given angle (x°) and the x-axis.**

*Reference Angles*If the terminal side of the the given angle,

**, falls on:**

*x°*

**Quadrant I: Reference Angle = x°**

*Quadrant II: Reference Angle = 180° - x°*

**Quadrant III: Reference Angle = x° - 180°****Quadrant IV: Reference Angle = 360° - x°**
