在解证几何问题时,有需要在图中另外添加一些辅助线,但许多初中生学生对添加辅助线往往是盲目而随意的,往往把简单问题复杂化。殊不知,辅助线只是我们的一种辅助手段,而不是目的,它是沟通已知和未知的桥梁,不能见到题目,就无目的地添加辅助线。一则没用、二则辅助线越多,图形越乱,反而妨碍思考问题。再者我们碰到的几何题并非一定要添加,就是要添也要从题意出发,才能达到辅助解题的意义。下面从几
There are additional guidelines that need to be added to the figure when deciphering geometry issues, but many junior high school students tend to be blind and casual about adding aids, often complicating simple questions. As everyone knows, auxiliary line is only an aid to us, not an end, it is to communicate the known and unknown bridge, can not see the subject, aimlessly add auxiliary line. A useless, two more auxiliary lines, the more chaotic graphics, but hindered thinking. Moreover, we encountered the geometric problem is not necessarily to add, that is, Tim also have to start from the title, in order to achieve the meaning of auxiliary problem-solving. From below a few
