Use vector Methods to Find Vertex of a Parallelogram

[smellymewi]

This saved me from completing raging at how inefficient my uni prof teaches maths. This is so much more clearer and easier to understand. Thanks :)

THANK YOU SO MUCH FOR THIS KNOWLEDGE!!!

This is very helpful. Thanks alot.


I also found an efficient method to this. You know how it's OC= OD+AB?
Move OD to the other side, which would be -OD or DO


DO+OC=AB
or DC=AB


However, I couldn't do it without this guy here. Thanks again!

Thank you so much sir for clarifying this💓👌

Why AB=DC ? they are not the same vector!
they are parallel I get that so AB = k DC
where k is some positive integer

But you are not finding the vertex C in this way. In case this might be a result of misinterpretation of english, in this case vertex means point. To find point c, because of the nature of parallelogram and its naming conventions DA = CB, do the equation and you’d get C (2, -1, 4)

What if I were to find D Instead of C?
