The lesson that I downloaded from the library would be of great benefit to my class during chapter 5. I love that the lesson I downloaded comes with a plan, guided practice, and a key so that I have everything required to do a lesson for that day. 
This lesson is really neat because it guides them into discovering why the 3 theorems SAS, ASA and SSS work to prove triangles are congruent and the kids discover this through accessing previous knowledge about rigid motions.
This lesson would be great for our geometry team-- especially if we plan to do a flipped classroom next year and we have our kids watch an introductory lesson before this practice.
