要提高立体几何的解题能力,除正确理解概念,掌握定理、公式外,还有一些常用的思考方法和技巧也应熟练地掌握和善于应用。一、类比就是通过某两个(类)事物的相似(近)性,推出它们在其他方面也可能相似或相同的一种推理方法。类比推理事实上是一种猜想,其结果当然有正有误,要通过实验或更严格的推理肯定或否定这种猜想。在立体几何的学习中借助类比有两个作 To improve the solving ability of solid geometry, in addition to the correct understanding of the concept, the mastery of theorems and formulas, there are also some commonly used thinking methods and techniques that should also be mastered and good at application. First, analogy is the introduction of a similar or similar method of reasoning in other ways through the similarity (nearness) of two or more things. Analogical reasoning is in fact a kind of conjecture, and the results are certainly wrong. It is necessary to affirm or deny such conjecture through experiments or more rigorous reasoning. There are two analogies in the study of solid geometry
