The Stammler circles - Jean-Pierre Ehrmann and Floor van Lamoen We investigate circles intercepting chords of specified lengths on the sidelines of a triangle, a theme initiated by L. Stammler. We generalize his results, and concentrate specifically on the Stammler circles, for which the intercepts have lengths equal to the sidelengths of the given triangle. ✪ ✪ ✪ ✪ ✪ Link tải tài liệu: LINK TẢI TÀI LIỆU Theo LTTK Education
