Let n ě 3 be an integer. Two regular n-gons A and B are given in the plane. Prove that the verti es of A that lie inside B or on its boundary are onse utive. (That is, prove that there exists a line separating those verti es of A that lie inside B or on its boundary from the other verti es of A.) (Cze h Republi )
