Unit 5 Quiz # 1 Review
Reviewing Transformationgs
2
Translations:
Remember: (x, y)
x -> + right, - left
y - + up, - down
Example: (x, y) -> (x - 5, y + 3)
3
Multiple Choice
How is the pre-image (red) translating to the image (blue)?
(x - 2, y + 3)
(x + 2, y - 3)
(x + 3, y - 2)
(x - 3, y + 2)
4
Multiple Choice
What are the new coordinates for A' if this triangle is translated (x - 2, y)
(1, -1)
(3, -1)
(-1, -1)
(1, -3)
5
Graphing
Translate each point (x + 3, y - 4)
A is (-4, 6)
B is (0, 0)
6
Reflections:
When reflecting over an axis, follow these rules:
Reflect over x-axis -> (x, -y)
Reflect over y-axis -> (-x, y)
Example: Reflect over y-axis.
7
Graphing
Reflect these points over the x-axis:
A (1, -2)
B (3, -4)
C (5, -6)
8
Graphing
Reflect this triangle over the y-axis.
Here's the points of the pre-image to help:
A(2, 3)
B(3, 1)
C(1, 2)
9
Rotations:
10
Rotations (Continued)
Example: Rotate 180 degrees
11
Multiple Choice
How did the pre-image (orange) transform into the image (green)?
Rotated 90 degrees clockwise
Rotated 180 degrees
Rotated 90 degrees counterclockwise
Rotated 270 clockwise
12
Multiple Choice
How is the pre-image (orange) rotated into the image (green)?
90 degrees clockwise
180 degrees
90 degrees counterclockwise
Reflected over the x-axis
13
Multiple Choice
How did the pre-image (blue) transform into the image (green)?
Reflected over the origin
Translated left by 2 and down 4
Rotated 180 degrees
Dilated by 2
14
Multiple Choice
What 2 transformations is moving A to B?
Translation then rotation
Rotation then translation
Reflection then rotation
Reflection then translation
