Using the point M_c and the point T_c, construct a line c (rule W02);

% DET: points M_c and T_c are not the same

Choose freely a point A on the line c (rule WOnline1)

Using the point A and the point M_c, construct a point B (rule W01);

Using the point A, the point B, the point T_c and the line c, construct a point T`_c (rule W19);

% NDG: points A and B are not the same points B and T_c are not the same points B and midpoint([A,T_c]) are not the same

Choose freely a point C on the circle k_over(T_c,T`_c) (rule WOncircle)
