Using the point H_b and the point H, construct a line h_b (rule W02);

% DET: points H_b and H are not the same

Using the point H_c and the point H, construct a line h_c (rule W02);

% DET: points H_c and H are not the same

Using the point H_b and the line h_b, construct a line b (rule W10a);

Using the line b and the line h_c, construct a point C (rule W03);

% NDG: lines b and h_c are not parallel

% DET: lines b and h_c are not the same

Using the point H_c and the line h_c, construct a line c (rule W10a);

Using the line c and the line h_b, construct a point B (rule W03);

% NDG: lines c and h_b are not parallel

% DET: lines c and h_b are not the same

Using the line b and the line c, construct a point A (rule W03);

% NDG: lines b and c are not parallel

% DET: lines b and c are not the same
