stay the same
Find the new coordinates of (3,-2) if you dilate the point with a scale factor of 4.
What is (12,-8)?
The picture below shows this type of transformation.
Rotation

(-2, 5)
The red shape is rotated _________ to create the blue image. (name both the degrees and direction
What is counterclockwise 90 degrees? or
What is clockwise 270 degrees?
When reflecting over the x-axis, which coordinate is now opposite?
y-coordinate
This is rule for the following translation:
(1, 5) -> (3, 0)
What is (x, y) -> (x +2, y - 5) ?
What transformation is not rigid?
dilation
What happens to the values in an ordered pair if a figure translates up and to the left.
What is the same as rotating 90o clockwise?
270o ccw
The figure has been reflected over this line.
What is the x-axis?
This rule describes rotating 270o clockwise.
What is (x,y) -> (-y, x)
Which axis is being reflected over? Which one is the original? Which one is the image (new figure)?
y-axis right to left
Describe in transformation notation how it was translated from pre-image to image. (x,y) --> (x+a,y+b)
left two units, up two units
(x,y) --> (x+2,y+2)
What is the ordered pair for M' after the figure below is rotated 90o clockwise?
(6, -6)
