射影几何中的共点线(共线点)定理的关系

The Connections of Concurent Lines (Collinear Points) Theorem in Projection Geometry

对射影几何中的共点线 (共线点 )定理之间的关系进行探讨 ,给出它们有关的对偶关系和等价关系 .

This paper discusses the relations between concurrent lines theorem and collinear points theorem of the projection geometry,and obtains their duality relation and equivalence relation.
