Step-by-step explanation:

The formula for distance between two points is

 \sqrt{(x2 - x1) ^{2}  + (y2 - y1) ^{2} }  \\ given \: points \: (a.b) \: and \: (b.a) \\  =  \sqrt{(b - a) ^{2} + (a - b) ^{2}  }  \\  =  \sqrt{ {b}^{2}  +  {a}^{2}  - 2ab +  {a}^{2}  +  {b}^{2} - 2ab }  \\  =  \sqrt{2 {a}^{2} + 2 {b}^{2} - 4ab  }  \\  =  \sqrt{2( {a}^{2}  +  {b}^{2} - 2ab) }  \\  =  \sqrt{2(a - b) ^{2} }  \\  =  \sqrt{2} (a - b) \\  =  \sqrt{2} a -  \sqrt{2} b
