In this activity students will cut strips of paper and assemble them into two-column proofs. There are three proofs that use triangle congruence postulates and CPCTC. A "Hints Sheet" is given for use with struggling students.
This activity could be used as an alternative assessment, a partner activity, or as a review before a test. I copy the student's sheet on colored paper and let them hang their finished product in the classroom.
Some of the proofs reasons used are listed below:
• SAS (Side-Angle-Side) Congruence Postulate
• SSS (Side-Side-Side) Congruence Postulate
• HL (Hypotenuse Leg) Congruence Postulate
• Definition of Perpendicular Lines
A digital, interactive version of this activity can be found here
. It is perfect for 1:1 classrooms!
