Find the distance between the following pairs of points :
(i) `(2, 3), (4, 1)`
(ii) `(– 5, 7), (– 1, 3)`
(iii) `(a, b), (– a, – b)`

Explanation

(i) Distance between (2,3) and (4,1)

`=sqrt((2-4)^2+(3-1)^2)`

`=sqrt(4+4)`

`=sqrt(8)`


(ii) Distance between (-5,7) and (-1,3)

`=sqrt((-5-(-1))^2+(7-3)^2)`

`=sqrt(16+16)`
