Question

Hint:

**Hint :-** use pythagoras theorem in triangle ABD and ABC

We get AC2 and AD2 subtract them and substitute BC = 2BD

In the equation to get the result.

## The correct answer is: Hence proved

### Aim :- Prove that

Explanation(proof ) :-

Applying pythagoras theorem in triangle ABC,we get

—- Eq1

Applying pythagoras theorem in triangle ABD ,we get

— Eq2

As AD is median , D is mid point then BC = 2BD

Subtract Eq1 - Eq2

We get ,

As D is mid point BD = CD ,

substitute BD = CD in the above equation

∴

Hence proved
