In this activity, students will cut strips of paper and assemble them into two-column proofs. The first two proofs are algebraic proofs, the third proof uses the segment addition postulate, and the fourth proof uses the definition of congruence. A "Hints Sheet" is included for 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.
Some of the proofs reasons are listed below:
• Substitution Property of Equality
• Symmetric Property of Equality
• Distributive Property of Equality
• Segment Addition Postulate
• Definition of Congruent Angles
A digital, interactive version of this activity can be found here
. It is perfect for 1:1 classrooms!
