    I meant Is -2pi / 3 = 240 degrees and its Degree Equivalent = 120 degrees ??

    What you can remember is that pi radians = 180 degrees

    I see another boo boo I mean Is -2pi / 3 = -240 degrees and its Degree Equivalent = 120 degrees??

    So you can replace pi with 180 degrees and simplify it \(\sf\Large \frac{-2(180)}{3}=?\)

    another way to think about it is: -2pi/3 we are working clockwise on the circle, and in radians the whole circle is 2pi so 2pi is also 6pi/3 and so to find out how much we are left at would be: 6pi/3 - 2pi/3 = 4pi/3

    -2pi/3 = -120 yes but this is at the 240 mark correct?

    and you can see from my second example that 4pi/3 = 240 degrees

    Ok lets start over. -2pi/3 = -120 degrees, which is at the 240 mark. Now its Equivalent degree is at 120, which is at 2pi/3 ??

    "-2pi/3 = -120 degrees, which is at the 240 mark." correct "Now its Equivalent degree is at 120, which is at 2pi/3 ??" and correct
