几何概型是高考考查的知识点之一,常以选择题、填空题出现.高考考查的重点是学生对化归与转化思想的领悟以及数形结合思想的应用,要求学生能将实际问题转化为相应的数学问题,再以“形”来解决“数”的问题,但是学生在备考当中,不能做到准确的识别,对此很有必要对几何概型问题进行辨析和解法研究.命题方向1:与区域长度有关的几何概型此类题目常以时间、角度和长度为载体进行命题,处理时只需把这个变量放在坐标轴上建立相应的几何概型求
Geometry profile is one of the knowledge points for college entrance examination, often multiple-choice questions, fill in the blank questions appear.The focus of the college entrance examination is the students understanding of conversion and conversion ideas and the application of mathematical combination of ideals require students to practical problems For the corresponding mathematical problems, and then to “shape ” to solve “number ” problem, but the students in the pro forma, can not be accurately identified, it is necessary for the analysis of the geometric model of the solution and solution Proposition Direction 1: Geometric Probes Related to Area Lengths Such topics often take propositions of time, angle and length as carriers, and only need to put this variable on a coordinate axis to establish the corresponding geometric requirements
