Dear Vaibhav

(1+(b-c)/a)a *(1+(c-a)/b)b *(1+(a-b)/c)c>= 1

every bracket is less than or equal to 1

but right hand side is greater than equal to 1

so its only possible when each bracket equal to 1

(1+(b-c)/a)=1

1+(b-c)/a =1

  b=c

 similerl from other brackets

 c=a

 a=b

 tiangle is equileteral
