Full Circle Protractors

1) Standard Radian Measures based on fractional parts of π. (StdRads)[br]2) Degree Measures based on the degree equivalents of above. (DegMks)[br]3) Decimal Radian Measures where 1 radian = 57.296° (DecRads)[br][br]Check Boxes for 1 & 2 can be both checked as the correlate well. The DecRads check box is best displayed alone.
