GeoGebra Proofs: SAS
During my search to find interactive proofs, I decided to create my own in GeoGebra. I wanted something low pressure and user-friendly to ease students into proving triangles are congruent. So I scrambled the statements and reasons so students can arrange the parts to complete the proof. The proofs could also be used as a whole class activity with a SmartBoard allowing volunteers to arrange the parts. Here are the links to the first proof and the second proof. I wasn’t able to quickly add the segment notation so I left it off, reminding the students that it should be there and the statements and reasons are typically numbered.
