Reflections and Rotations!

If you’d like to play more with the Geogebra models we used in class today, here are links to the model for rotations and reflections.

I modified the rotations model with a suggestion from Cooper so that it is less tedious to move points in the pre-image. I apologize for not having the reflection model ready to use during class, but do recommend you take some time to experiment with it and believe what your new-found algebraic rules tell you.
