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

Using the point G and the point H, construct a point O (rule W01);

Using the point M_c and the point O, construct a line m_c (rule W02);

% DET: points M_c and O are not the same

Using the point C and the point O, construct a circle k(O,C) (rule W06);

% NDG: points C and O are not the same

Using the point M_c and the line m_c, construct a line c (rule W10a);

Using the circle k(O,C) and the line c, construct a point A and a point B (rule W04);

% NDG: line c and circle k(O,C) intersect
