How would you interpret this question?
Now I know how to get orthogonal vectors when you're given another vector, and I know how to do it when you're give two points. However I have been given this question, and I'm not entirely sure what it's asking. Hopefully someone here can point out what I'm missing.

Given a vector in 2D space as V1, how would you calculate an orthogonal vector for points A and B?
Thanks for the help.

Orthogonal vector for a point doesnot make any sense, does it ?
You can have orthogonal to a line or a plane, but point?

Exactly! You see why I'm confused?

I wonder if it would be okay to assume points A and B make up vector V1.

Unfortunately, I cannot really ask the giver of this question what they meant.

Yup. I hope that's what they meant. Or else its some new kind of mathematics. :)
