Two vectors are perpendicular if the dot product is 0. So for example a cross b = c
So then a dot c should equal 0 and the same should go for b dot c. So if both do equal zero it must mean they do satisfy the rule correct?
EDIT: Ok nvm that does not help me out at all in my question.
1. Homework Statement
Let a=(1,2,3) b=(-1,2,-1) and c=(0,1,-2). Do these vectors taken in this order, satisfy the right hand rule? Explain.
3. The Attempt at a Solution
I was told a cross b must equal c otherwise this is not satisfying? I'm VERY confused...can someone help out...
