200
These are the types of transformations that do not change the size.
What are reflections, translations, and rotations?
200
Adding a positive number to the x-coordinate moves a figure in this direction.
What is to the right?
200
This is the coordinate M' after the figure below is rotated 180o clockwise.
What is (-6, -6)?
200
The figure has been reflected over this line.
What is the x-axis?
200
Angles 4 & 6, and angles 3 & 5 are this.

300
The picture below shows this type of transformation.
What is rotating?
300
This is the image coordinate pair when the preimage (1, 6) is translated to the left 3 and down 1.
What is (-2, 5)?
300
This clockwise rotation is the same as rotating 90o counterclockwise.
What is 270o clockwise?
300
This is the coordinate A' after the figure below has been reflected over the given line.
What is (6, 1)?
300
Angles 1 & 7, and angles 2 & 8 are this.
What are alternate exterior angles?
400
This notation(symbol) is how we differentiate the preimage from the image.
What is prime (small tick mark)?
400
This mathematical operation happens to the x coordinate if a figure translates to the left.

400
The measure of the angle of rotation of ABCD about the origin. 
What is 270 degrees CCW or 90 degrees CW
400
The given graph depicts this rigid transformation over this line.

400
Angles 2 & 6, and angles 3 & 7, and angles 1 & 5, and angles 4 & 8 are this.
What are corresponding angles?
500

500
The given graph depicts this rigid transformation this number of degrees in this direction. (grey to red)
What is a 90-degree clockwise rotaition?
500
The distance between the pre-image and the line of reflection, and the image and the line of reflection, are always this.
What is the same?
500
Angles 1 & 3, angles 2 & 4, angles 6 & 8, and angles 5 & 7 are these.
What are vertical angles?
600
