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.
