this is for my mechanics course, but its just dealing with vectors. sorry if this is in the wrong place. 1. The problem statement, all variables and given/known data The problem is: You are given two vectors (4,0) and (0,4) that form the sides of a parallelogram. Determine the vectors that constitute the diagonals of this parallelogram and show by means of vector properties that they intersect each other at right angles. 2. Relevant equations 3. The attempt at a solution I'm assuming that you start at the origin for the vectors. Then you would add the vectors, so the diagonals would be (4,4). I'm not sure if both diagonals would be (4,4). Once I have the diagonals, I think that you would take the dot product and if it equals 0, then that would prove that they intersect at right angles.
