Using the point O and the point Ma, construct a line ma (rule W02);
% DET: points O and Ma are not the same
-
Using the point O and the point Mc, construct a line mc (rule W02);
% DET: points O and Mc are not the same
-
Using the point Ma and the line ma, construct a line a (rule W10a);
-
Using the point Mc and the line mc, construct a line c (rule W10a);
-
Using the line c and the line a, construct a point B (rule W03);
% NDG: lines c and a are not parallel
% DET: lines c and a are not the same
-
Using the point B and the point Ma, construct a point C (rule W01);
-
Using the point Mc and the point B, construct a point A (rule W01);
