Investigating Congruent Triangles (Original)

This is an activity that uses both Desmos and Web Sketchpad. In the first part of the activity students investigate the nature of triangle congruency by using an external websketch to manipulate triangles. Once they discover all of the congruency rules then there are some practice problems which they can do to see if they understand them. This will likely take two periods The reason that both Web Sketchpad and Desmos are used is so that you have the dynamic nature of the triangles via Web Sketchpad along with the ability to capture student thinking via Desmos Activity Builder.
