In a triangle A B C, take the tangent to the circumcircle of A B C at A. Reflect this line through the angle bisector at A. prove that this reflected line is parallel to B C.
I'm looking for a quick and simple proof of this fact.

The tangent is anti paralel to B C since its angles are oposite to the triangle A B C, because the semi inscribed angles. A reflexion to the angle bisector inverses the angles,so that the angles corresponds to the triangle's direction.
