1. Editing module and problem-solving method: Version A mainly uses axioms, theorems and auxiliary lines to solve solid geometry problems, with more emphasis on traditional methods, while Version B introduces the knowledge of vectors, uses the methods and concepts of space vectors to solve solid geometry problems, and algebraically makes the problem-solving process more modern and algebraic.
2. Key points: version A pays more attention to the examination of spatial imagination and thinking, helping students to establish geometric intuition, while version B pays more attention to revealing the essence of concepts, improving mathematics literacy, and helping students to have a deeper understanding and understanding of mathematics.
3. Version B contains many contents and is difficult. In addition to the basic knowledge points, version B also contains some deeper and more complicated contents, especially some difficult problems and exercises, such as group B exercises, which are very difficult and suitable for students who have a strong interest in mathematics or need in-depth study.
