Can I get help starting this exercise:-

Let triangle ABC be such that AB is not congruent to AC. Let D be the point of intersection of the bisector of angle A and the perpendicular bisector of side BC. Let E, F, and G be the feet of the perpendicular dropped from D to line AB, line AC, line BC.

Prove that:-

D lies outside the triangle on the circle through ABC.
