数学是区内学生较头疼的科目,几何更是难中之难,很多孩子能把定理性质背得滚瓜烂熟,但一到题目中很难转换成自己需要的知识,近日因初三复习的需要,整理了初中几何复习资料,觉得在整个初中几何学习中,辅助线起了画龙点睛的作用,往往能使图形更直观地帮助我们完成解题过程。在此,简要地讲讲几道利用辅助线解得几何题。
Mathematics is more headache subjects in the region, the geometry is more difficult, many children can go back to the nature of the theorem, but it is difficult to convert to the knowledge they need, recently because of the need for review, Finishing junior high school geometry review information, think geometry throughout the junior high school learning, auxiliary line plays a finishing touch, often make graphics more intuitive help us to solve the problem process. Here, briefly talk about using the auxiliary line to solve geometry problems.
