Using a straightedge and a compass, and given a line $$\lambda$$ and a point $$A$$ on the line, what is the minimum number of moves required to construct a line which makes a $$30 ^ \circ$$ angle with line $$\lambda$$ which passes through point $$A$$?

All terminology in this question is explained in Wen Z's note. Credits to Wen Z for making the note..
