[考试要求] 立体几何是高中数学的重要内容之一。在历年高考中所占比例大约20％,试题中通常要考一个大题,四个小题,合计30分左右。立体几何包括两个部分:“直线与平面”和“多面体与旋转体”。国家教委考试中心颁发的《考试说明》明确规定了“直线与平面”部分有21个知识点,“多面体与旋转体”部分有13个知识点,并提出了具体的考试要
[Examination Requirements] Three-dimensional geometry is one of the important contents of high school mathematics. In the college entrance examination over the years, the proportion of about 20%, test questions usually have to test a big question, four small questions, a total of about 30 minutes. Solid geometry consists of two parts: “straight and flat” and “polyhedron and rotating body.” The “Exam Description” issued by the National Education Commission Examination Center clearly stipulates that the “straight and plane” part has 21 knowledge points, and the “polyhedron and rotating body” part has 13 knowledge points, and puts forward specific examination requirements.
