What is sliding or moving up, down, left, or right?
Another way to describe a reflection
What is flipping or mirroring?
Another way to describe a rotation
What is spinning?
DOUBLE: Another way to describe a dilation
What is resizing or making a shape bigger/smaller?
Dilating with a scale factor of 2 makes the image
