Solution

Let X be any point on side AB.

Given that, XMABandXNAC

To prove that, TX2=TB.TC

Proof:- BNXM

Now,

In ΔTXM,By using Basic proportionality theorem, we have

TBTX=TNTM......(1)

Now,

In ΔTCM, By using Basic proportionality theorem, we have

TXTC=TNTM......(2)

By equation (1) and (2) to, we get

TBTX=TXTC

TB.TC=TX2

TX2=TB.TC

Hence proved.
