3. I would only want the diagonal to separate in the two different directions.

9. What I ended up doing was creating line segments to match the whole figure and tried to create the animations in this order:
Show the whole figure
Place the line of symmetry
The figures go into two separate directions and come back (that is not happening for me  )
It took me forever to just do the horizontal line – which is when I ed you guys
I wanted to show the vertical, diagonal then horizontal line of symmetry

13. Same as in slides 7 and 8
