Tóm tắt

The congruent triangles content relates to various geometric and algebraic knowledge. One challenge for math pedagogical students in learning and preparing for teaching this content is connecting theorem knowledge to identifying exercises types and methods of solving exercises within this topic. This article presents two directions in teaching students of Mathematical pedagogy to construct different types and solutions to  congruent triangles exercises, namely: based on theorem logical structure and based on deductive method. The results  would help students recognize the basis of designing problem types and solutions, as well as the relationship with 7 congruent triangles theorems. It is believed that clarifying the relationship between theorems and problem types and solving methods would clarify the origin of the problem types and the solving methods for students, which would promote their interest in teaching theorems.
