Using the point C and the point Hc, construct a line hc (rule W02);
% DET: points C and Hc are not the same
-
Using the point C and the point Ta, construct a line a (rule W02);
% DET: points C and Ta are not the same
-
Using the point Hc and the line hc, construct a line c (rule W10a);
-
Using the line c and the line a, construct a point B (rule W03);
% NDG: lines c and a are not parallel
% DET: lines c and a are not the same
-
Using the point B, the point C, the point Ta and the line a, construct a point T`a (rule W19);
% NDG: points B and C are not the same points C and Ta are not the same points C and midpoint([B,Ta]) are not the same
-
Using the point Ta and the point T`a, construct a circle k_over(Ta,T`a) (rule W09);
