Define a Translation
Sliding of an image.
Define a reflection.
Mirror Image; when you flip an image across a line of symmetry
Define rotation
Moving something about a fixed point clockwise or counterclockwise; to turn or spin an image
Define a dilation
Scaling a preimage to enlarge or shrink it. Has a scale factor.
Identify the transformation.
Dilation

Did the original image get larger or smaller?
larger
Identify the transformation.

A(3,-4) translate it 3 units to the left and 4 units up. What is A'?
(0,0)
If the figure is I(5,-2) reflected over the x-axis, what are the coordinates of I'?
(5,2)
What are the coordinates with a 180 degree clockwise rotation of the point (4,-2) about the origin?
(-4,2)
What would H' be if the point H(-12,16) had a dilation with a scale factor of 1/4?
(-3,4)
Which two transformations are represented in the image?
Dilation and Reflection
What word can you make shorter by adding two letters?
Short
After a translation, the coordinates of J' are (4,-1). If J is (2, 2), what was the translation?
2 units right. 3 units down.
G(-4,-4) goes to G'(-4, 4). Which axis did the point reflect across?
x-axis
What are the coordinates with a 270 degree clockwise rotation of the point (4,-2) about the origin?
(2,4)
Triangle ABC has vertices A(0, 4), B(-1, 4), and C(0, -3). What are the coordinates of B' after a dilation with a scale factor of 4?
(-4, 16)
Which transformation would create the following frieze pattern?
Rotation

All of them
The ordered pair R(-2, 7) is translated 5 units to the right and down 2 units. Write an equation to describe the translation.
ex: (x, y) -- (x - 3, y + 2)
(x + 5, y - 2)
If Triangle RST is reflected over the y-axis, then again over the x-axis, what would be the location of T'?
(-8, 7)
If Triangle RST rotated 90o clockwise around the origin, which quadrant would it land in?
III
Point A is (3,6) and Point A' is (1,2). What was the scale factor of the dilation?
1/3
Describe the transformation(s) which occurred from the preimage to the final image. The more specific you are (and correct), the more points you receive.
First, Triangle ABC is dilated with a scale factor of 1.5, then it is rotated 90o counter-clockwise around the origin.
