胡适先生留下治学名言:“大胆猜想,小心求证”.这对我们解决判断说理题有很好的启发作用,因为对于判断说理题来说,读题之后,需要根据直觉作出合理、合情的猜想,再对自己提出的猜想或直觉进行严谨的求证,有时甚至要推翻初始的猜想,获得另外的结论.下面结合一道考题讲解这类问题的解题策略.例题(2014·福建泉州)如图1,在锐角三角形纸片ABC中,AC>BC,点D、E、F分别在边AB、BC、CA上.
Mr. Hu Shi left the famous saying of learning: “bold guess, careful verification ” This is a very good enlightenment for us to solve the problem-solving theory, because to judge the reasoning problem, after reading the question, we need to make reasonable according to intuition Passion conjecture, and then to their own conjecture or intuition rigorous confirmation, and sometimes even to overthrow the initial guess, get another conclusion. The following combination of a test questions to explain the problem solving strategies .Example (Quanzhou, Fujian Province in 2014) As shown in FIG. 1, in acute triangle paper ABC, AC> BC and points D, E and F are on the sides AB, BC and CA, respectively.
