This doesn't change during a rigid transformations.
What is the size?
The word that describes translating.
What is sliding?
The word that describes rotating
What is turning?
This word is another way of saying reflecting
What is flipping?
These are the types of rigid transformations.
What is to the right?
Making both coordinates negative rotates the figure this many degrees.
What is 180o (clockwise or counterclockwise)?
This is the same in the image, preimage, and line of symmetry in a reflection.
What is the distance from the figure to the line of symmetry?
The picture below shows this type of transformation.

What is rotating?
This is the image coordinate pair when the preimage (1, 6) is translated to the left 3 and down 1.
What is (-2, 5)?
The segment below has been rotated 90o in this direction.

What is counter clockwise?
This coordinate changes when a figure is reflected over the x-axis.
What is the y-coordinate?
