Question

Hint:

**Hint :-** Using pythagoras theorem in triangle ABC and ADB we find AC2 and AD2 and substitute the value of AD2 In AC2 equation to get the required result.

## The correct answer is: Hence proved

### Aim :- Prove that

Explanation(proof ) :-

As AP is median we get PB = BC also PB^{2 }= BC^{2}

Applying pythagoras theorem in triangle APB we get

Applying pythagoras theorem in triangle ABC we get

Adding and subtracting PB^{2} we get ,

Substitute

Hence proved
