Reflection: Flexibility Rigid Motions and Congruence - Section 2: Mini-Lesson

 

As I was teaching, I realized my students had some difficulty identifying corresponding parts of triangles and their images. I decided to address their issues before we continued with the lesson. Students were instructed to draw and label diagrams in their notebooks to illustrate how the specific rigid motion preserved congruence between the triangles and their images. This helped my students better understand the topic and helped me to assess their understanding of the new content.
