关于比例线段证明的思路探索

Study on the Thinking of Proportional Segments Demonstration

几何证题思路是几何证明中的一个极其关键的问题,本文以典型问题:关于比例线段为例,阐述了如何探索和开拓几何证明的思路,怎样运用和发展思路,进而创新新思路、新方法。以达到提高和掌握几何论证规律,为此本文提供了一些方法和见解。

The thinking of demonstrating problems using geometric methods is a quite key problem. In this paper are detailedly expounded how to search the thinking of geometric demonstration, how to use and develop the thinking and following the creation of new thoughts and methods for improving and understanding the law of geometric dem-onstration. So this paper takes the typical problem-On the proportional segments as a ex-ample to present some methods and understandings.
