In the past, a test paper had to examine 90 knowledge points, and the coverage rate was about 70%, which was regarded as one of the criteria to measure the success of the test paper. This tradition has been broken in recent years, replaced by attaching importance to thinking, highlighting ability, and attaching importance to the examination of thinking methods and thinking ability. Now we are happier in math than our predecessors! ! Finally, I suggest you visit this website often, www.pep.com.cn, and I believe it will be helpful to your study. Wish you success! Try the outline of the preliminary competition of the national senior high school mathematics league, which is completely in accordance with the teaching requirements and contents stipulated in the full-time middle school mathematics syllabus, that is, the knowledge scope and methods stipulated in the college entrance examination, and the method requirements are slightly improved, among which the probability and calculus preliminary tests are not taken. Test 1, basic requirements of plane geometry: master all the contents determined by the outline of junior high school mathematics competition. Supplementary requirements: area and area method. Several important theorems: Menelius Theorem, Seva Theorem, Ptolemy Theorem and siemsen Theorem. Several important extreme values: the point with the smallest sum of the distances to the three vertices of a triangle-fermat point. The center of gravity is the point where the sum of squares of the distances to the three vertices of a triangle is the smallest. The point where the distance product of three sides in a triangle is the largest is the center of gravity. Geometric inequality. Simple isoperimetric problem.
