-
Using the point Hb and the point Tb, construct a line b (rule W02);
% DET: points Hb and Tb are not the same
-
Using the point Hb and the point Ma, construct a circle k(Ma,B) (rule W06);
% NDG: points Hb and Ma are not the same
-
Using the circle k(Ma,B), the line b, the point Ma and the point Hb, construct a point C (rule W05);
% NDG: line b and circle k(Ma,B) intersect
% DET: points Hb and C must be different
-
Using the point C and the point Ma, construct a point B (rule W01);
-
Using the point Ma and the point C, construct a line a (rule W02);
% DET: points Ma and C 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 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
