Question

What is the distance between the points A (c, 0) and B (0, −c)?

 

Answer 1

We have to find the distance betweenA( c , 0)  and B (0 , - c) .

In general, the distance between A`(x_1 , y_1) " and B " (x_2 , y_2)` is given by,

`AB = sqrt((x_2 , x_1)^2 + ( y_2 - y_1)^2)`

So,

`AB = sqrt((c - 0)^2 + (0 - c)^2)`

     ` = c sqrt(2)`
