and then rotate the second point say 180 degrees around the origin ?

Hi Art,

You can definitely find the angle in the first part of your question. As far as rotation, I have to think a little more. Should be possible though.

Are you rotating one of your LED displays? If so, are we talking full rotation, or just 90, 180, 270 degrees?
