Geometry

Vijay calculated the area of triangle ABC. Then I asked him to calculate  the area when angle A is doubled with the lengths of the arms  AB and AC of angle A being unaltered. He said there is no change in area.His calculations are perfect. 

You know it is possible when angle A = 60°.Prove it GEOMETRICALLY.
