If PAB is a secant to a circle intersecting the circle at A and B and PT is a tangent,prove that PA X PB = PT2 . Using the above, prove the following: Triangle ABC is an isosceles triangle, such that AB=AC and the point D is the mid-point of AC. A circle is drawn taking BD as diameter,which intersects AB at E. Prove that AE= 1/4AC.
