Using the point Hc and the line c, construct a line hc (rule W10b);
-
Using the line hc and the line b, construct a point C (rule W03);
% NDG: lines hc and b are not parallel
% DET: lines hc and b are not the same
-
Using the point A, the point C, the point Tb and the line b, construct a point T`b (rule W19);
% NDG: points A and C are not the same points C and Tb are not the same points C and midpoint([A,Tb]) are not the same
