The attached document gives all students (especially struggling students) a place to start when diving into a triangle congruency proof.
Print one out for each student to have has a reference, print a large one out to place as an anchor poster in the room, or project on a document camera for kids to create their own.
These 5 steps really gave my lower students access to proofs. I noticed that many were missing problems because they started the proof without successfully marking up the triangle. This resource helps mitigate that tendency.
