Reference Angles for Quadrantal Angles

[ckfletcher]

I have to do a "wheel" with the degrees and radians for a circle starting with 0 degrees/0 radians all the way around for increments of 45, 30, and 60. I also have to find the reference angle for all of these angles in degrees and radians. I understand how to find the reference angles for all of the angles except for the quadrantals (0, 90, 180, 270/ 0, pi/2, pi, 3pi/2, and 2pi) Thanks so much

Well, do it. This is a common memorization exercise. I do not believe you can receive much help on your art work. Scan an image and let us see how it goes.
