If 1 is the incentre and `I_1,I_2,I_3` are the centre of escribed circles of the `triangleABC`. Prove that
`II_(1)^(2)+I_2I_(3)^(2)= II_(2)^(2)+I_(3)I_(1)^(2)= I_(1)I_(2)^(2)+II_(3)^(2)`

Text Solution

Verified by Experts

The correct Answer is:
`II_(1)^(2)+I_2I_(3)^(2)= II_(2)^(2)+I_(3)I_(1)^(2)= I_(1)I_(2)^(2)+II_(3)^(2)`
