These things don't change during a rigid transformation.
What is the size and shape
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?
What is special about translations that isn't true for rotation and reflection?
Preserves orientation
These are the types of rigid transformations.
What is to the right?
How do you rotate 180 degrees?
If the line of reflection is x=, will it be horizontal or vertical?
vertical
Angle A in Triangle ABC is 45 degrees. ABC is rotated 90 degrees clockwise then translated 5 units up. What is the measure of Angle A'?
45
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?
Rectangle QRST is translated 10 units left and 1 unit down then reflected across the y-axis. If Angle R was 90 degrees, what is the measure of Angle R'?
90 degrees
This notation is how we differentiate the preimage from the image
What is prime notation?
This is what happens to the coordinates if a figure translates up and to the left.
What is subtracting from the x-coordinate and adding to the y-coordinate?
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?
4 units
This figure is the image in the following reflection:
What is the blue figure?
The shapes are translated in this direction these many units.
What is left two units, up to units?
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)?
When describing a reflection, we must include what?
The line we reflect over
