What is Rigid Transformation
100
A type of transformation that changes the size of a figure.
What is a Dilation
100

The rule for a reflection across the x-axis.
What is (x, y) --> (x, -y)
400
Figure ABCD is located at the following coordinates:
A: (0, 3)
B: (0, 6)
C: (9, 12)
D: (12, 6)
Figure ABCD is dilated with a scale factor of 1/3 with the center of dilation at the origin. Find the coordinates of the dilated image.
What is:
A': (0, 1)
B': (0, 2)
C': (3, 4)
D: (4, 2)
400
The scale factor of the dilation shown in the coordinate plane:
What is a scale factor of 1/2
(k = 1/2)
400
Are the following figures similar? Why or why not? Show/explain your reasoning.
No because if you compare the corresponding side lengths, they are not proportional.
ex:
30/15 = 2
20/10 = 2
12/4 = 3
