Vì a,b,c là 3 cạnh tam giác nên a,b,c là 3 số dương
À mà bạn biết tính chất này chứ a/(a+b+c)<a/(b+c) (Cộng vào mẫu a dương nên nhỏ hơn)
a/(b+c)<(a+a)/(a+b+c)=2a/(a+b+c) (Cộng cả tử với mẫu với a)
=> Ta có: a/(a+b+c)<a/(b+c)<2a/(a+b+c) (1)
Tương tự với b: b/(a+b+c)<b/(a+c)<2b/(a+b+c) (2)
Tương tự với c: c/(a+b+c)<c/(a+b)<2c/(a+b+c) (3)
Cộng (1) với (2) và (3) ta được đpcm
1< a/(b+c) + b/(a+c) + c/(a+b) <2
bạn chỉ cần làm tương tự thôi
