Problem 32 from Wernick's corpus

Problem 32 from Wernick's corpus: A, O, H_a

Given a point A, a point O and a point H_a, construct the triangle ABC.

ArgoTriCS says that the problem is solvable.

Using the point A and the point H_a, construct a line h_a (rule W02);

% DET: points A and H_a are not the same
Using the point A and the point O, construct a circle k(O,C) (rule W06);

% NDG: points A and O are not the same
Using the point H_a and the line h_a, construct a line a (rule W10a);
Using the circle k(O,C) and the line a, construct a point C and a point B (rule W04);

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