Hi!
I just joined this group and I have a problem, which I want you to
help me solve. I have to prove that in a triangle ABC, if the angle
bisector of A meets the perpendicular bisector of BC at P, then the
point P lies on the circumcircle of triangle ABC. In other words,
quadrilateral ABCP is cyclic!
PLEASE HELP!
Thanks in advance
