4.6 Explore the similar conditions of triangles. The second volume of Grade 8 Mathematics of Beijing Normal University Edition explains that this lesson is divided into two classes. The first lesson mainly allows students to explore three conditions of triangle similarity, and the second lesson mainly allows students to flexibly use the conditions of triangle similarity. If students' interest in exploration has just been aroused, it will be transferred to applied teaching, which is not conducive to the cultivation of students' interest. It is better to let the exploration go through and explore the other two conditions. In the second class, when two triangles are proved to be similar, students' comprehensive analysis ability can also be cultivated, and three proof methods can be selected. ...
