1. Editing module: Version A uses axiomatic theorems and other traditional geometric methods as auxiliary lines to solve solid geometry problems, while Version B uses space vector methods and concepts to solve solid geometry problems.

2. Key points: Version A is suitable for self-learners or students who don't have so high requirements for high school mathematics, and pays attention to the examination of spatial imaginative thinking. Version B pays more attention to revealing the essence of concepts and improving mathematics literacy, and is suitable for students who are interested in mathematics.
