% Domain   : Geometry (Oriented curves)
% Problem  : Subcurves with common endpoint can be complemented
% Version  : [EHK99] axioms.
% English  : Every proper sub-curve of an open curve that has a common
%            endpoint with the open curve can be complemented by another
%            curve so that their sum constitute the open curve.
