Solve
(1) Two circles with centres M and
N intersect each other at P and
Q. The tangents drawn from
point R on the line PQ touch the
circles at S and T.
Prove that, RS = RT.

Answer 1

Step-by-step explanation:

join MS and TN

now from theorem i.e., the radius is always perpendicular to tangent such that RT and RS are tangents drawn from a single point R

so from theorem I.e., the lengths of tangents drawn from any single external point are equal

RS = RT
