动态几何问题以几何变化为主,因其解法比较复杂而经常作为中考的压轴题目出现,动态几何问题之所以复杂是因为其集几何、函数、方程、不等式等于一身,考察学生数学的综合能力.这类问题对学生的数学基本功要求较高,所以要省时省力的解决此类问题前提是要有扎实的数学功底,在平时学习中学生也要锻炼自己的空间想象能力和演绎推理能力. Dynamic geometry is dominated by geometric changes. Because of its complicated solution, it often appears as a finale of senior high school entrance examinations. The reason why dynamic geometric problems are complex is that their geometric, function, equation, and inequality are equal to each other. Such questions have higher requirements on students’ math basic skills. Therefore, to save time and labor, the premise of solving such problems is to have a solid mathematical foundation. In normal times, middle school students also need to exercise their own space imagination ability and deductive reasoning ability.
