A vector is a direction and a length. Where you "connect" them depends on what you want to do.If there are two vector in a given plane and they are not connected tail to tail then what we have to doo. I think now we have to connect the two vectors tail to tail by the smallest angle theta so that we can have a vector perpendicular to both the vectors. Correct me if I am wrong

E.g. a force has a direction and an amount. Whether you can use it to pull the chair depends on where you apply the force.

I think you're on the right track. Cancel the word "smallest" and it looks ok. The angle is defined by the directions the vectors point. There is no smallest or biggest. Of course you have to put them tail to tail to determine the angle between them.

Slide the vectors to have their tails meet, then measure the angle from the first vector to the second vector.

Then you'll take the sine of that angle.

In three dimensions, if this area is nonzero,

there will be a unique line that is perpendicular to that parallelogram.
