Show that if a circle with centre A intersects a circle with centre B in two
distinct points P and Q, then the line through AB is the perpendicular
bisector of the segment PQ. Please help!!!

Difficult to explain without showing a picture. A basic theorem is that if you draw a triangle in a semicircle with the hypotenuse as the diameter then the 3rd vertex on the edge of the circle is always a right angle. Since right angles are perpendicular, manipulating that will give you what you need.http://www.algebra.com/algebra/homework/Circles/Theorems-on-Triangle-and-Circle.lesson
