[tex]a) |AB| = \sqrt{( - 2 + 2 {)}^{2} + (4 + 5 {)}^{2} } = \sqrt{0+ {9}^{2} } = \sqrt{81 } = 9[/tex]
[tex]b) |CD| = \sqrt{( - 1 - 5 {)}^{2} + (1 - 1 {)}^{2} } = \sqrt{( - 6 {)}^{2} + 0} = \sqrt{36} = 6[/tex]
[tex]c) |EF| = \sqrt{(5 - 2 {)}^{2} + (3 + 3 {)}^{2} } = \sqrt{ {3}^{2} + 0 } = \sqrt{9} = 3[/tex]
