Is it possible one dimensional plane?

    I have heard about two or above dimensional plane which we can express R2 or Rn. But I never heard about one-dimensional plane which we can express R.

    Is it possible one dimensional plane?

    Well, that's because we don't use the word "plane"! A one dimensional "plane" is a "line".
