A: Junior high school geometry can best exercise people's imagination and logical thinking ability. Geometry is not difficult, but the combination of numbers and shapes is not clear. I can't remember the definition theorem of geometry. In fact, there is no need to memorize properties, theorems, inferences, etc. Instead, by doing more exercises, we constantly use theorem definitions, graphic properties and judgment theorems; If you do more questions, you will naturally remember them. Just like talking to someone on the phone often, you don't need to remember his phone number. If you make too many phone calls, you will naturally think of the same reason. Junior high school geometry should include plane geometry and solid geometry. Solid geometry is not difficult, mainly depends on spatial imagination. There are many problems with plane geometry, because there are too many problems that plane geometry can be made into comprehensive types.

Plane geometry extends from points to lines, which include straight lines and line segments. Based on the parallelism of straight lines, parallel lines are divided into proportional line segments, and the equal ratio theorem, including the bisection theorem, is produced. There are line segments leading to triangles and special line angles, and the contracts of triangles are identical and similar; Therefore, a series of judgment theorems and inferences have been produced. From triangle to quadrilateral, trapezoid (special trapezoid), parallelogram and special parallelogram-square, rectangle and diamond, their properties and judgment theorems are summarized. Plane curves are mainly circles. Don't want to say too much, too much to remember. Geometry was not taught by others, but learned by myself. On the issue of "learning" and "learning", we rely more on our own "learning" and it is difficult to "learn" well. This is "the master leads the door and practices in the individual". There is no shortcut to any knowledge. You have to practice by yourself. To learn a knowledge well, it is not enough to finish the homework left by the teacher. You must find some difficult problems to practice yourself in order to get high. In fact, each teacher gives lectures in a different way, but what he teaches is the content of the syllabus. So students from different places learn basically the same things. If there is any ambiguity, always ask the teacher's opinion, and then consider whether what the teacher said is acceptable or unacceptable. You can ask the teacher again. After understanding the teaching content, calm down and do the questions; By doing problems, constantly summarizing, systematizing knowledge and mastering problem-solving skills, thus improving the speed of solving problems.

The best teacher tells you ten times, it is better to do it yourself. Basic principles of learning knowledge. One's own potential depends on oneself, and no one else can help or replace it. This is also the basic truth that students can surpass teachers, but teachers can't surpass students; Because the teacher hasn't done the problem for several years. Therefore, practice is the best way for students to learn and master knowledge.
