使学生掌握一些解题、证题的规律和方法是数学教学的一个重要方面,本文就下列两种类型的几何证明题谈谈自己粗浅体会. 一、关于a~n=b·c·d…e(n≥2,n∈N)型结论的证明 1.当n=2时(a~2=bc)的证明方法及步骤:
It is an important aspect of mathematics teaching to enable students to master some laws and methods of solving problems and questions. This paper talks about the following two types of geometric proof questions and discusses their own superficial experiences. I. About a~n=b·c·d... Proof of e (n ≥ 2, n ∈ N) type conclusions 1. Prove method and step when n=2 (a~2=bc):
