    Where do we end up if we start at 0° and perform a 2550° clockwise rotation?;

    2550/360 = 255/36 = (252 + 3)/36 = (252/36) + (3/36) = 7 + (1/12) rotations. We end up (1/12)(360°) clockwise past 0° ie., 30° clockwise past 0°. We end up exactly where we would've landed if we'd started at 0° and rotated counter-clockwise 330°.

    So, out of all the choices of equivalences you have provided, only one, which I just

    related, fits the bill.
