立体几何的本质在于研究空间图形中的位置关系——通过三维空间,认识空间图形.人们通常采用直观感知、操作确认、思辨论证、度量计算等方法认识和探索几何图形的特征及其性质,它在构建直观、形象的数学模型方面有其独特的作用,这就必然地成为高考不可或缺的考查内容之一.本文以本质的立体几何的考查为视角,评析近年各省市数学高考的相关试题.
The essence of solid geometry lies in the study of the positional relationship in the spatial graph - to recognize the spatial graph through the three-dimensional space.People usually recognize and explore the characteristics and properties of the geometric graph by means of intuitionistic perception, operational confirmation, speculative argumentation and metric calculation It has its own unique function in constructing an intuitive and vivid mathematical model, which inevitably becomes one of the indispensable examinations of the college entrance examination.This article takes the examination of the essential three-dimensional geometry as the angle of view to analyze the related questions of the mathematics entrance examinations of various provinces and cities in recent years .
