Let a be (5,_2)&b be (6,_4)and c (7,_2). Distance between A and B=root under (6_5)^2+(_4+2)^2 Root under1+4=root under5. Distance between A and C=root under (7_5)^2+(_2+2)^2=root under4=2. Distance between B and C=root under (7_6)^2+(_2+4)^2= root under1+ 4= root under5. Hence distance of AB=distance of BC=root 5
