立体几何是高中数学的核心模块之一,在近几年各地高考和模拟测试中,除了传统的证明和计算外,一类以“动手”为特征的立体几何问题引起了广泛关注,我们不妨将其称为实验性几何问题.下面我们从实例出发探讨此类问题的一般解决思路.
Three-dimensional geometry is one of the core modules of high school mathematics. In addition to the traditional proofs and calculations in various college entrance examinations and simulation tests in recent years, a class of three-dimensional geometric problems characterized by “hands” attracted widespread attention. Let’s call it an experimental geometric problem. Here we start with examples to discuss the general solution to such problems.
