% Domain   : Geometry (Oriented curves)
% Problem  : Unique oppositely oriented curve 2
% Version  : [EHK99] axioms.
% English  : For every oriented line there is exactly one uniquely determined
%            oriented line with the same underlying curve that orders the
%            points in the opposite way.
