-
Using the point A and the point Ha, construct a line ha (rule W02);
% DET: points A and Ha are not the same
-
Using the point Ha and the line ha, construct a line a (rule W10a);
-
Using the point I and the line a, construct a circle k(I,Pa) (rule W11);
% NDG: point I is not incident to the line a
-
Using the circle k(I,Pa), the point A and the point I, construct a line c and a line b (rule W12);
% NDG: point A is outside the circle k(I,Pa)
-
Using the line c and the line a, construct a point B (rule W03);
% NDG: lines c and a are not parallel
% DET: lines c and a are not the same
-
Using the line a and the line b, construct a point C (rule W03);
% NDG: lines a and b are not parallel
% DET: lines a and b are not the same
