Use the distance formula to find the distance between points C (5,6) and D (2,2).
d=[tex]\sqrt{(x2-x1)^2+(y2-y1)^2}[/tex]
Plug the corresponding values in to the equation.
d=[tex]\sqrt{(2-5)^2+(2-6)^2}[/tex]
Then simplify the rest of the equation.
d=[tex]\sqrt{(-3)^2+(-4)^2}[/tex]
d=[tex]\sqrt{9+16}[/tex]
d=[tex]\sqrt{25}[/tex]
d=[tex]5[/tex]
The distance of the two points CD is 5.
