Collinearity of the first trisection points of cevian segments - Francisco Javier Garcia Capitan We show that the first trisection points of the cevian segments of a finite point P are collinear if and only if P lies on the Steiner circum-ellipse. Some further results are obtained concerning the line containing these first trisection points. ✪ ✪ ✪ ✪ ✪ Link tải tài liệu: LINK TẢI TÀI LIỆU Theo LTTK Education
