Supplementary Angles

This version of supplementary angles highlights three elements sometimes forgotten in showing angles. [b]1/ that 0 degrees is naturally "North" or 12 o'clock, but 0 degrees is actually the turn between one line and the next or its new position. 2/ That degrees are generally measured clockwise, and that they are a measure of turn 3/ Why does supplementary end at 180. Is there a word for supplementary applied to 360[/b]
