Playlist
By the end of this playlist I can...
...define and recognize translations, reflections and rotations
...perform a given translation, reflection or rotation in the coordinate plane
...determine the transformation that maps a pre-image to an image
...use algebraic rules to describe transformations in the coordinate plane (x, y) → ( , )
