This doesn't change during 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?
A triangle has this many degrees
What is 180?
These are the types of transformations that do not change the size.
What are reflections, translations, and rotations?
Adding a positive number to the x-coordinate moves a figure in this direction.
What is to the right?
This is the coordinate M' after the figure below is rotated 180o clockwise.
What is (-6, -6)?
The figure has been reflected over this line.
What is the x-axis?
Angles 4 & 6, and angles 3 & 5 are this.
What are alternate interior angles?
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)?
This clockwise rotation is the same as rotating 90o counterclockwise.
What is 270o clockwise?
This is the coordinate A' after the figure below has been reflected over the given line.
What is (6, 1)?
Angles 1 & 7, and angles 2 & 8 are this.
What are alternate exterior angles?
This notation(symbol) is how we differentiate the preimage from the image.
What is prime (small tick mark)?
This mathematical operation happens to the x coordinate if a figure translates to the left.
What is subtracting?
The measure of the angle of rotation of ABCD about the origin.
What is 270 degrees CCW or 90 degrees CW
The given graph depicts this rigid transformation over this line.
What is a reflection in the y-axis?
Angles 2 & 6, and angles 3 & 7, and angles 1 & 5, and angles 4 & 8 are this.
What are corresponding angles?
This color figure is the image in the following reflection:
What is the blue figure?
The shapes are translated in this direction these many units. (green to purple)
What is left two units, up two units?
The given graph depicts this rigid transformation this number of degrees in this direction. (grey to red)
What is a 90-degree clockwise rotaition?
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?
Angles 1 & 3, angles 2 & 4, angles 6 & 8, and angles 5 & 7 are these.
What are vertical angles?
This rule describes rotating 270o clockwise.
What is (x,y) to (-y, x)?
The graph depicts this rigid transformation this number of units in these directions.
What is a translation 1 unit right 2 units down?
A point on the preimage is (1,2). What are the coordinates of the image after a 270 degree clockwise rotation?
What is (-2,1)
A point on the preimage is (1, 2). What are the coordinates of the point of the image after a reflection across the y-axis?
What is (-1, 2)?
Alternate interior angles, alternate exterior angles, corresponding angles, and vertical angles are all this.
What is congruent?
