“构造法”是创造性思维,它没有固定的模式,是因题而异的.构造法解题是利用知识之间的内在联系或形式上的某种相似性,有目的构造一个特定的数学模型,使问题在模型的作用下实现转化,达到解题的目的.现以三角题为例说明. Constructive law is a creative thinking, it has no fixed pattern, is due to the problem varies constructive problem solving is the use of knowledge of the internal connection or form of a certain similarity, a purpose to construct a specific Mathematical model, so that the problem under the effect of the model to achieve the purpose of solving problems. Now Triangle as an example.
