This doesn't change during a rigid transformations.
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?
If I said to move to move a figure up 6 spaces what type of transformation did I do?
Translation
These are the types of rigid transformations.
Which direction for a translation makes the x-coordinate bigger?
right
Making both coordinates negative rotates the figure this many degrees.
What is 180o (clockwise or counterclockwise)?
This is the line that reflects a shape.
Line of reflection
What type of transformation flips a shape?
Reflection
The picture below shows this type of transformation.
Rotation
What are the new coordinates of a point when the point (1, 6) is translated to the left 3 and down 1?
(-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?
What transformation turns a shape?
Rotation
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)?
Where is the line of reflection?
x-axis
What is true about angles if two parallel lines are cut by a transversal?
The angles are equal.
Is the red or blue figure the original shape?
Red figure
The shapes are translated in this direction these many units.
left two units and up two units
or
up two units and left two 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)?
What is it called when a transformation doesn't change a shapes size or angle measures
Rigid tranformation
