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);

Choose freely a point C on the line h_c (rule WOnline2)

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);
