All angles start at the right hand side of the x-axis.
Positive angles rotate from there going COUNTER-clockwise,
and negative angles rotate from there going CLOCKwise.

First you draw a +130° angle, starting at the right side of
the x-axis and rotate counter-clockwise:



Then add -360° and get 130°+(-360°) and get -230°. 

So to draw a -230° angle, we start at the right side of
the x-axis and rotate CLOCKwise, indicated by the
blue arc:
