Question

In a triangle ABC, AB²

+AC² = 200cm and median AD=10cm. Find BC.​

Answer 1

Answer :-

10

Full Explanation :-

Answer 2

Step-by-step explanation:

Since,

AB²+BC²= 2(AD²+BD²)

Therefore,

let BD= x

200= 2(10²+x²) [By Appolonius Theorem]

100= 100+x²

x²= 0 (i.e. the side doesn't exist)

Therefore, The Triangle doesn't exist.
