This is an activity to help students visualize overlapping triangles. It is perfect for a congruent triangles unit! I had my high school geometry students add it to their interactive notebooks to help them through the triangle congruence proofs.
My geometry students love these proof activities! They are the perfect alternative to a worksheet to help my high school math students get hands on proof practice. I especially love the activity for parallel lines proofs and congruent triangles proofs.
