In figure 11.24. two tangents are drawn to a circle.
from a point A which is in the exterior of the circle.
The points of contact of the tangents are P and Q as
shown in the figure. A line / touches the circle at R
and intersects AP and AQ in B and C respectively.
If AB = c, BC = a, CA = b, then prove that
(1) AP + AQ = a + b + c
(2)
AB + BR = AC + CR = AP = AQ = a + b + c upon 2
