First, geometric figure analysis: point, line and surface

Point: intersection point, distance.

Lines: intersecting, parallel.

Face: triangle, circle, etc.

Point-line problem: distance formula.

Line and surface problems: intersection point and tangent point.

Point problem: inside and outside.

These questions are the finale.

Thinking of solving problems: 1. Decompose complex problems into point, line and surface problems.

2. Introduction of division method: All of them are divided into triangles and quadrangles, which are solved by properties and judgment theorems.

It's like the decomposition of physical forces.

Second, analytic geometry problems: parabola and straight line are the key points.

1, equation memory, understanding and application.

2. Intersection and intersection.

3. Two-point distance formula.

4. The equation is transformed into pattern group in mathematical calculation.

I hope I can bring you ideas, in short, relax, be careful, be rigorous and process.

Good luck in the middle school entrance examination!
