Ahhh it all makes sense. Yes, thank you.

And the orthogonal complement of a line in 3D is another line, too? Is a plane ever the orthogonal complement of something?

@JulianP: You're right! I guess that's the problem?

@user84413: I'm sorry, I didn't know that. I have added the basis. $\left\{ \left ( \begin{matrix} 1 & 0 \\ 0 & 1 \end{matrix}\right ) , \left ( \begin{matrix} 0 & 1 \\ 1 & 1 \end{matrix} \right )\right \}$

@user156384: No. It may have been an error I guess. Just curious if perhaps there were multiple coordinate vectors (can there be?)
