-
Using the point B and the point Tc, construct a line c (rule W02);
% DET: points B and Tc are not the same
-
Using the point Tb and the line c, construct a circle k(Tb,foot[Tb,c]) (rule W11);
% NDG: point Tb is not incident to the line c
-
Using the circle k(Tb,foot[Tb,c]), the point B, the point Tb and the line c, construct a line a (rule W13);
% NDG: point B is outside the circle k(Tb,foot[Tb,c])
-
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 Tb and the point Tc, construct a line b2 and a line b (rule W12);
% NDG: point Tb 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
-
Using the line a and the line b, construct a point C (rule W03);
% NDG: lines a and b are not parallel
% DET: lines a and b are not the same
