学以致用 回归生活——三角形的“五心”在现实生活中的应用探究

Learning in Order to Practice and Returning to Life:Exploration the Application of the "Five Centers" of Triangle to Real Life

运用数学知识解决生活实际问题是学生的数学素养之一。数学教学要贴近生活,培养学生运用数学知识解决实际问题的能力。本文通过对三角形内心、旁心、外心、重心和垂心的概念和性质的简述,探究了它们在现实生活中的应用,以期提高数学教学的实用效果。

To use mathematical knowledge to solve practical problems is one of the mathematical qualities of students. Mathe- matics teaching should be close to students＇ life, so as to train their ability to use mathematical knowledge to solve practical problems. Through a brief introduction to the definitions and properties of the ＂five centers＂ of triangle, this paper explores their application to real life, hoping to improve the practical effect of mathematics teaching.
