On the Newton line of a quadrilateral - Paris Pamfilos We introduce the idea of the conjugate polygon of a point relative to another polygon and examine the closing property of polygons inscribed in others and having sides parallel to a conjugate polygon. Specializing for quadrangles we prove a characterization of their Newton line related to the possibility to inscribe a quadrangle having its sides parallel to the sides of a conjugate one. ✪ ✪ ✪ ✪ ✪ Link tải tài liệu: LINK TẢI TÀI LIỆU Theo LTTK Education
