Projective space
In mathematics, a projective space can be thought of as the set of lines through the origin of a vector space V. The cases when V = R and V = R are the real projective line and the real projective plane, respectively, where R denotes the field of real numbers, R denotes ordered pairs of real numbers, and R denotes ordered triplets of real numbers.
