This is an activity for proofs that prove triangles are congruent by SSS, SAS, AAS, and ASA. You can print this activity, which The file includes 4 proofs and two problems with algebra- finding the value of a variable using congruent figures. You can print this activity and cut out the statements and reasons on the proofs. I put each picture at a station in my room along with the cut out statements and reasons, and the kids used the pieces to create the proof. You could also put a magnet on the cut-out pieces and students could arrange the proof on a magnetic board.
