Take spaces A and B of non col linear straight lines passing through origin in $R^2$ though $dim A = dim B$ ,but we cant conclude that A⊆B. They have only one point in common that is zero vector. Am i right sir?

Straight lines are of dimension 1 in $R^2$ . It seems as my conclusion is wrong.

Can't i apply these theprems on Banach space operators?

It's general result. My main concern is can we apply these theorems in Banach space as well?
