I love love love this booklet!!! I was just looking for an activity that gave congruency statements and required the students to mark the triangles and found this goldmine!!! I wish I had found this a day earlier as we already had started two-column proofs with no "hints". Every single class asked why we didn't do this before doing it the "other way". I love this book! Anyone have any tips on printing it correctly.

I have read in a few sources that congruence is often badly taught in schools, and that most students do not have a very strong grasp of what congruence is. Maybe they can convince themselves by drawing pictures but that doesn't demonstrate they fully understand. This bothers me - what is the point of learning how to prove two triangles are congruent if one does not understand why the proof works?
