平面几何中有一类问题,要求在线上或平面内找出若干个符合要求的点,我们不妨称之为“找点问题”.这类问题往往有一定难度,主要是难以找到问题的突破口和切入点.线上或平面内有无数个点,哪个点或哪些点是符合要求的,学生往往难以寻找和确定,因而无从下手.本文谈谈如何抓住问题的本质,帮助我们找到相应的解题策略和方法. There is a type of plane geometry problems that require online or in the plane to find a number of points that meet the requirements, we may wish to call “Some problems ” This type of problem is often a certain degree of difficulty, mainly difficult to find a breakthrough And point of entry. There are a number of points on the line or in the plane, which point or points are in line with the requirements, students are often difficult to find and determine, and therefore can not start .This article talk about how to seize the essence of the problem, help us find the corresponding Problem-solving strategies and methods.
