Question

If ad is median of triangle abc then the value of ab+ac/ad

Answer 1

Answer:

We have,

InΔABC,AB=AC.and AD is the median.

Then prove that,

InΔABC,AD is the perpendicular bisector of BC.

Proof:-

In

ΔADBandΔADC

AB=AC(Giventhat)

AD=AD(Commonline)

∠ADB=∠ADC(Everyrightangle)

Then, ΔADB≅ΔADC by S.A.S. rule

So, AD is the perpendicular bisector of BC.

Hence proved.
