The outline of the preliminary test competition of the national senior high school mathematics league matches 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 are slightly improved, and the preliminary test of probability and calculus is not taken.
Second division
1, plane geometry
Basic requirements: master all the contents of junior high school mathematics syllabus.
Supplementary requirements: 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 center of gravity is the point in the triangle where the distance product of three sides is the largest.
Geometric inequality.
Simple isoperimetric problem. Understand the following theorem:
In the set of N-polygons with a certain circumference, the area of the regular N-polygon is the largest.

198 1 year, chinese mathematical society began to hold the "National Senior High School Mathematics League". After three years of practice, this mass mathematics competition has been welcomed by middle school teachers and students, educational administrative departments at all levels and science and technology associations. At the same time, all localities have put forward the requirements of holding the "National Junior Middle School Mathematics League". 1984, chinese mathematical society Popularization Committee agreed to entrust Tianjin Mathematics Association to hold junior high school mathematics invitational tournament. At that time, 14 provinces, municipalities and autonomous regions participated. At the third popularization meeting of the Chinese Mathematical Society held in Ningbo on June 5438+065438+ 10 of that year, the decision to hold the "National Junior Middle School Mathematics League" was unanimously adopted, and some specific measures were agreed in detail, stipulating that the "National Junior Middle School Mathematics League" should be held on the first Sunday of April every year.
The "National Junior Middle School Mathematics League" originally did not distinguish between the first test and the second test. 1July, 989, in Jinan, representatives from all over the country agreed that the junior middle school league should also have a second trial, and clearly defined the number of various types of questions and scoring standards for the first and second trials.
