```										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)a  =1
1+(b-c)/a =1
b=c
similerl from other brackets
c=a
a=b
tiangle is equileteral
