Question

22. What is the distance between two points (a,b) and (-a,b)?
​

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

)

2

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

=

(−a−a)

2

+(−b−b)
