The Olympic Method of Mathematics in Senior High School
First of all, I will give you an outline of the high school mathematics Olympic Games.

High school mathematics olympiad outline?

Just try it.

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 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 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. ? In a set of simple closed curves with a certain perimeter, the area of the circle is the largest. ? In a group of N-sided polygons with a certain area, the perimeter of the regular N-sided polygon is the smallest. ? In a set of simple closed curves with a certain area, the circumference of a circle is the smallest. ? Motion in geometry: reflection, translation and rotation. ? Complex number method and vector method. ? Planar convex set, convex hull and their applications. ?
