#### Storyboard Text

• Good Morning class! Today we will be learning about Reference Angles!
• Stop complaining this will prepare us for the final in May!
• Ugh! Ms.Smith we've already learned enough math this year!
• I'm just here for attendance...
• So what is a Reference Angle? It's the angle that the given angle makes with the x-axis. No matter where the angle ends, the reference angle measures the closest distance of that terminal side to the x-axis.
• When on a graph, positive angles go in a clockwise direction. Well of course negative angles go in a counter clockwise direction.
• Every positive angle in Quadrant 1 is acute, so the reference angle is the measure of the angle itself.
• To find the reference angle measuring (x) degrees for an angle in Q3, the formula is 180 degrees- (x) degrees.
