Using the point O and the point G, construct a point H (rule W01);
-
Using the point Ha and the point H, construct a line ha (rule W02);
% DET: points Ha and H are not the same
-
Using the point Ha and the line ha, construct a line a (rule W10a);
-
Using the point O and the line a, construct a line ma (rule W10b);
-
Using the line ma and the line a, construct a point Ma (rule W03);
% NDG: lines ma and a are not parallel
% DET: lines ma and a are not the same
-
Using the point Ma and the point G, construct a point A (rule W01);
-
Using the point A and the point O, construct a circle k(O,C) (rule W06);
% NDG: points A and O are not the same
-
Using the circle k(O,C) and the line a, construct a point C and a point B (rule W04);
% NDG: line a and circle k(O,C) intersect
