Description

In this READY TO PRINT proofs activity, students will write three triangle congruence geometry proofs. Your students will love this HANDS-ON ACTIVITY.

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

• CPCTC

etc.

A digital, interactive version of this activity can be found here. It is perfect for 1:1 classrooms!

This is part of my Geometry Proofs Cut-Out Bundle. Check it out!
