几何第一、二两章是平面几何的基础,这两章的教学应该十分注重概念的教学,重视培养学生识图和理解、表述几何语言的能力,同时要进行推理论证的渗透训练。为此,我们配合现行课本,编写了一套课堂练习题。这些练习题可用作各课时新课结束后的巩固练习,也可用作新课前的复习练习。第一章基本概念1.1 直线1.读句画图: (1)点P在直线AB上,点M在直线AB外。(2)直线AB、CD相交于O,点N在AB上,
The first and second chapters of geometry are the basis of plane geometry. The teaching of these two chapters should pay great attention to the teaching of concept, attach great importance to cultivating students' ability to understand, express and understand the geometry language while conducting penetrating training of reasoning and argumentation. To this end, we co-operate with the current textbooks and write a set of classroom practice questions. These exercises can be used as a consolidation exercise after the new lesson ends in each lesson, or as a review exercise before the new lesson. The first chapter of the basic concepts of 1.1 straight line 1. read the sentence: (1) point P in the straight line AB, the point M outside the straight line AB. (2) Line AB, CD intersect at O, point N at AB,
