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

% DET: points M_c and H_c are not the same

Using the point H_c and the line c, construct a line h_c (rule W10b);

Using the point M_c, the line h_c and the point H_c, construct a line h_Mc,1/3(h_c) (rule W15);

Choose freely a point G on the line h_Mc,1/3(h_c) (rule WOnline4)

Using the point G and the point M_c, construct a point C (rule W01);

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);
