| Abstract: | As an effort to enlarge the scope of projective geometry,the present paper is an attempt to use projective transformation to map circle into proper quadratic curve,so as to develop and generalize the Butterfly Theorem into aprojection geometry proposition,one of the most impotant Euclidean geometry(a branch of the projective geometry itself)theorems related with circle. |
