The graphic position relationship mainly includes the relationship between points, lines, triangles, rectangles/squares and circles. The senior high school entrance examination will be included in the problems of function, coordinate system and geometry, but mainly through the relationship between circle and other figures, among which the most important ones are various problems of circle and triangle.

2. Dynamic geometry

One is algebraic synthesis. There are moving points and moving straight lines in the coordinate system, which are generally solved by multivariate functions. The other is the geometric synthesis problem, in which moving points, moving lines and overall translation are set in trapezoid, rectangle and triangle to investigate the comprehensive analysis ability.

3. Solve the practical application of right triangle.

Usually, based on real life, we investigate the ability of using right-angled triangle knowledge to establish a mathematical model, and use the mathematical idea of "straightening when leaning", that is, use auxiliary lines to transform it into a right-angled triangle problem, and then list the equations according to the relationship between known conditions and unknown elements, and solve them by using the knowledge of solving right-angled triangles.

4. Correlation calculation of shadow area

This kind of problem often combines knowledge of transformation, function and similarity, and involves mathematical thinking methods such as transformation and entirety, which is very comprehensive.

5. Synthesis of linear function and inverse proportional function.

There are generally three questions. The first question often examines the method of undetermined coefficient to determine the quadratic resolution function. The second question examines the quadratic resolution function and its maximum value in combination with the perimeter, area and line length of the triangle. The third question is mostly about the exploration of geometric figures.
