Two Inequalities for the Medians and the Symmedians of a Triangle;
涉及三角形中線與類似中線的兩個(gè)不等式
The R-r-s method of triangle inequality is employed to prove the conjecture of a triangle inequality proposed by the author many years ago,which is the reciprocal inequality for median ma,mb,mc,the circumradius R and the radius of the inscribed circle r:1/ma+1/mb+1/mc≤2(1/R+1/r)/3.
采用三角形不等式中R-r-s方法,證明了作者多年前提出的一個(gè)有關(guān)三角形的猜想不等式,即有關(guān)中線ma,mb,mc與外接圓半徑R以及內(nèi)切圓半徑r的不等式:1/ma+1/mb+1/mc≤2(1/R+1/r)/3。
The important method of R-r-s is used to prove the inequality chain for the medians altitudes and radii of exinscribed circles of a triangle:Let ma,mb,mc denote the medians of the triangle ABC;the altitudes ha,hb,hc;the radii of exinscribed excircles ra,rb,rc;then holds maha+mbhh+mchc≥wbwc+wcwa+wcwa≥hara+hbrb+hcr.
應(yīng)用重要的R-r-s方法,證明了有關(guān)銳角三角形的中線、高線與旁切圓半徑的不等式鏈:設(shè)銳角ΔABC的三條中線,三條高線與旁切圓半徑分別為ma,mb,mc;ha,hb,hc和ra,rb,rc,則成立不等式:maha+mbhb+mchc≥wbwc+wcwa+wawb≥hara+hbrb+hcrc。
