Using the point B and the point Ta, construct a line a (rule W02);
% DET: points B and Ta are not the same
-
Using the point Tb and the line a, construct a circle k(Tb,foot[Tb,c]) (rule W11);
% NDG: point Tb is not incident to the line a
-
Using the circle k(Tb,foot[Tb,c]), the point B, the point Tb and the line a, construct a line c (rule W13);
% NDG: point B is outside the circle k(Tb,foot[Tb,c])
-
Using the point Ta and the line c, construct a circle k(Ta,foot[Ta,c]) (rule W11);
% NDG: point Ta is not incident to the line c
-
Using the circle k(Ta,foot[Ta,c]), the point Tb and the point Ta, construct a line b1 and a line b (rule W12);
% NDG: point Tb is outside the circle k(Ta,foot[Ta,c])
-
Using the line b and the line a, construct a point C (rule W03);
% NDG: lines b and a are not parallel
% DET: lines b and a are not the same
-
Using the line c and the line b, construct a point A (rule W03);
% NDG: lines c and b are not parallel
% DET: lines c and b are not the same
