【Abstract】 In this paper, through the analysis of the relation between Pascal theorem and Steiner theorem, Pappus theorem and Desargues theorem,the writer gives out the major directing function of Pascal theorem in proje-ctive geometry.And in this paper the writer also raises some suggestions about -the treatmento of Pascal theorem for the writing of the projective geometry textbooks.更多还原
