A pole is fixed vertically on a plane. An ant while walking on the plane, observes that its angle of elevation to the top of the pole is 45^ . Then it walks 1 m straight towards the pole, turns left and then moves 2 m further. If it finds the angle of elevation is again 45^ , then the height of the pole is
