在中学数学内容中 ,相似三角形占有十分重要的地位 ,它把已学的直线形由“等”的研究变成“比” ,提高了学生对抽象思维能力的要求。而其中又以如何利用成比例线段的有关性质进行证明较为复杂 ,本文介绍的移比法就为其中一种常见的重要证明。熟练掌握这一方法 ,并能一题多解 ,?
In secondary school mathematics, similar triangles occupy a very important position, it has been learned from the “equal” research into “ratio”, improve the students’ ability to abstract thinking. However, it is more complicated to demonstrate how to use the related properties of proportional segments. The shift ratio method introduced in this paper is one of the most important and important proofs. Proficiency in this method, and can be more than one solution,?
