Teaching Overlapping Triangle ProofSummary:
The file starts with a two minute video that shows how to do the proof with the moveable parts. This can be shown to the students, or the teacher can view the video to see how to explain the concept to the class. If the teacher views the video, then the teacher can use the ink file triangles to do a live demo, or have a student do a live demo. Hopefully, with color coding, and showing how the triangles are congruent, the proof will be much easier to understand.
