Let PT be a tangent to the circle from an external point P and a secant to the circle through P intersects the circle at points A and B, then PT 2 = PA × PB
Using the above result prove thr following.
Triangle ABC is an isoceles triangle , such that AB = BC ,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
Its urgent Please help Sir
For students : thumbs up for sure.
