数学应用题一直是数学中考命题长盛不衰的热点问题,而以现实生活为背景的几何应用题更是受到越来越多中考命题者的青睐。此类问题具有取材新颖、立意巧妙、背景熟悉的特点,给人一种身临其境的亲切感。解决此类问题需要自觉地运用几何知识去观察、分析、抽象、概括所给的实际问题,揭示其数学本质,并转化为我们所熟悉的几何模型,利用数学思想和方法加以解决。中考几何应用问题的学习,可以让我们感悟数学思想和方法的魅力。一、设计几何图形方案中的分类思想
Mathematical problem has always been a hot topic in mathematics test scores, but the real life as the background of the geometric problem is more and more applications in the senior high school entrance examination who favor. Such problems have a novelty, cleverly intended, background familiar characteristics, giving a person an immersive intimacy. To solve such problems, we need to conscientiously use the knowledge of geometry to observe, analyze, abstract and summarize the actual problems we have given. We can reveal the mathematical essence and transform it into the familiar geometric model and solve it by using mathematical ideas and methods. The application of the exam in the geometric study, we can understand the charm of mathematical ideas and methods. First, the classification of geometry design concept
