On Projective 3-Space

Abstract

The purpose of this work is to give some definitions and prove some theorems onprojective 3-space S=PG(3,K) over a field K.Also, the principle of duality in S is given which state that any theorem true in theprojective 3-space concerned with the points, planes and the incidence relation, the sametheorem is true by interchanging "point" and "plane" whenever they occur, where as thedual of a line is a line.
