Question

4. Suppose P and Q are the centres of two disjoint circles C1 and C2 respectively,
such that P lies outside C2, and Q lies outside C2. Two tangents are drawn
from the point P to the circle C2, which intersect the circle Ci at points A and
B. Similarly, two tangents are drawn from the point Q to the circle C1, which
intersect the circle C2 at points M and N. Show that AB = MN.​
