A translation is when you do what to a figure?
Slide or Move the figure right, left, up, or down
A reflection is when you do what to a figure?
Flip it or make a mirror image of it.
A rotation is when you do what to a figure?
Turn or Spin
What about a shape will not change when you apply a Reflection, then a Translation.

What are three types of transformations?
Translation, rotation, reflection, or dilation.
