    Please help with symmetry question

    In a triangle ABC, AB = AC and D is a point on AC such that AD = DB = BC. Find the size of the angle BAD? Find the angles of triangle ABC?

    Just need a few hints to get this problem started please?

    I have ADB being isoceles where AD=DB but from there how do you mesure angle A? I know that A and B will be the same in that triangle but how do u get a value?

    Also angle B = angle C as AB = AC but just cannot figure it out?

    Please help
