we define the distance between A and B as :
or either
![d(C,D)=d[(-2,1),(2,4)]=\sqrt{(-2-2)^{2}+(1-4)^{2}}=\sqrt{(-4)^{2}+(-3)^{2}}=\sqrt{16+9}=\sqrt{25}=5](/tpl/images/0128/3916/acef3.png)
![d(D,E)=d[(2,4),(5,0)]=\sqrt{(2-5)^{2}+(4-0)^{2}}=\sqrt{(-3)^{2}+(4)^{2}}=\sqrt{9+16}=\sqrt{25}=5](/tpl/images/0128/3916/64e19.png)
![d(E,F)=d[(5,0),(1,-3)]=\sqrt{(5-1)^{2}+(0-(-3))^{2}}=\sqrt{4^{2}+3^{2}}=\sqrt{16+9}=\sqrt{25}=5](/tpl/images/0128/3916/d7ccc.png)
![d(F,C)=[(1,-3),(-2,1)]=\sqrt{(1-(-2))^{2}+(-3-1)^{2}}=\sqrt{3^{2}+(-4)^{2}}=\sqrt{9+16}=\sqrt{25}=5](/tpl/images/0128/3916/a853d.png)
