Question

distance between the points (a ,b) and ( b, a)
​

Answer 1

Answer:

Distance between two points (x

1 ,y 1 ) and (x 2,y 2 ) can be calculated using the formula (x 2 −x 1 ) 2+(y 2−y 1 ) 2

Therefore, distance between the points (a,b) and (−a−b) is

= (−a−a) 2 +(−b−b) 2

= 4a 2 +4b 2

=2 a 2+b 2
