Secondary conclusions and model inductions are commonly used in junior high school mathematics
1. Dart model, angle bisector model
2. Hand-in-hand model, half-width model
3. Truncate length complements the short, and times the length of the middle line
4. Projective theorem, round power theorem
5. Ptolemy's theorem
6. Inverse scale function model
