coordinate system - Does the Chamberlin trimetric projection map (some) great circles to straight lines?


Chamberline trimetric projection from wikipedia


I know that, in general, the Chamberlin trimetric projection maps most great circles on the sphere to some sort of non-straight curve on the flat map.


But what about the 3 special great circles that go through each pair of the 3 control points of the Chamberlin trimetric projection? Does the Chamberlin trimetric projection map those 3 great circles to straight lines on the flat map?
