Using the point C and the point Ma, construct a point B (rule W01);
-
Using the point C and the point Ma, construct a line a (rule W02);
% DET: points C and Ma are not the same
-
Using the point Tc and the point B, construct a line c (rule W02);
% DET: points Tc and B are not the same
-
Using the point Tc and the line a, construct a circle k(Tc,foot[Tc,b]) (rule W11);
% NDG: point Tc is not incident to the line a
-
Using the circle k(Tc,foot[Tc,b]), the point C, the point Tc and the line a, construct a line b (rule W13);
% NDG: point C is outside the circle k(Tc,foot[Tc,b])
-
Using the line b and the line c, construct a point A (rule W03);
% NDG: lines b and c are not parallel
% DET: lines b and c are not the same
