The graphics are Microsoft Smart Art graphics and can be easily changed to match your school colors or presentation theme. Here, the unit circle presented as a collection of divisions in radians first by eighths, then by twelfths and then as a division in angles first by 45 degrees, then by 30 degrees. Each radian fraction flies in as a fraction over 4 so students can see how the divisions of a unit circle are 1/4, 2/4, 3/4, 4/4, 5/4, 6/4, 7/4, and 8/4 and then these radians are simplified.
