-
Using the point O and the point Mb, construct a line mb (rule W02);
% DET: points O and Mb are not the same
-
Using the point Ha and the point Mb, construct a circle k(Mb,C) (rule W06);
% NDG: points Ha and Mb are not the same
-
Using the point Mb and the line mb, construct a line b (rule W10a);
-
Using the circle k(Mb,C) and the line b, construct a point C and a point A (rule W04);
% NDG: line b and circle k(Mb,C) intersect
-
Using the point Ha and the point C, construct a line a (rule W02);
% DET: points Ha and C are not the same
-
Using the point C and the point O, construct a circle k(O,C) (rule W06);
% NDG: points C and O are not the same
-
Using the circle k(O,C), the line a, the point O and the point C, construct a point B (rule W05);
% NDG: line a and circle k(O,C) intersect
% DET: points C and B must be different
