ABCD is a parallelogram with vertices A=(-1,2,-1), B=(2,-1,3), and D=(-3,1-3), find the coordinates of C.
So this is my work below, BUT i cannot seem to get the correct coordinates of C, as my diagram does not seem to look exactly like a parallelogram..
I sketched A, B, D..
A is on the y-axis , D is below it to the right and in 4th quadrant, B is in second quadrant.. so I assumed that C would be in 2nd qadrant.
The vector AC= The vector DB
since they are parallel
