“空间中的距离和角”是高考的必考知识点,在高考试卷中一般是中等难度试题。空间中的距离包括点点距、点线距、点面距、线线距、线面距、面面距等,其中点面距是考查的重点;空间的角包括线线角、线面角、面面角,其中线面角、面面角是考查的重点。尽管考查这部分知识的是中等难度试题,但学生得分并不理想。如何通过二轮专题复习实现对这部分难点知识有效的突破,我们的经验是在注重“通性、通法”的基础上,精心选择、设计典型习题并认真剖析,从以 “Space in the distance and angle ” is the entrance exam knowledge point, in the college entrance examination papers are generally moderate difficulty questions. The distance in space includes the point-to-point distance, the point-line distance, the distance from the point, the line-line distance, the line- Face angle, of which line angle, corner is the focus of examination. Although examining this part of knowledge is a moderate difficulty test, students score less than ideal. How to achieve effective breakthrough in this part of difficult knowledge through the review of the second round of special subject? Our experience is to carefully choose and formulate typical exercises based on the principle of “generality and common law”
