The geometric model of senior high school entrance examination refers to the commonly used model in geometric problems that often appear in middle school mathematics examinations. These models can help students better understand problems and provide ideas and methods for solving problems.

The following are some geometric models commonly used in the senior high school entrance examination:

Affinity theorem; Angular bisector theorem; Median line theorem; Intersecting chord theorem; Chord tangent angle theorem; Secant theorem; Cutting line theorem; 12345 model; The general drinks horses; Site selection of bridge construction; The general walks the horse; A line with a third angle; The dot circle is the most valuable, and the line circle is the most valuable; Hu Bugui; A circle; Hand in hand model; Chicken claw model; Pull-foot mode; Brahmagupta model; Half-angle model; Ptolemy theorem; Ptolemy infinitive; Guadou principle; Acquaintance mode;

These geometric models often appear in mathematics of senior high school entrance examination. Mastering their properties and application methods can help students solve problems better and improve their scores. Therefore, in preparing for the exam, we should focus on mastering these geometric models, and carry out related exercises and problem-solving training to improve the problem-solving ability and test-taking ability.
