Your students will love this HANDS-ON ACTIVITY! In this READY TO PRINT proofs activity, students will write three proofs about parallel and perpendicular lines.

In this activity, students will cut strips of paper and assemble them into two-column proofs. There are three proofs that deal with parallel lines with transversals and parallel and perpendicular lines. The theorems are given with theorem names or as the theorems are written out, depending on your preference. A "Hints Sheet" is given to help 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 sheet on colored paper and let them hang their finished product.

Some of the proofs reasons used are listed below:

  • Corresponding Angle Congruence Thm.
  • Alternate Interior Angle Congruence Thm.
  • Perpendicular Transversal Thm.
  • Lines Perpendicular to a Transversal Thm.
  • 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!
