Question

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

 

Answer 1

We have to find the distance between A (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)`

`= csqrt(2)`
