Transformations

A type of transformation where a figure is “flipped” over a line of symmetry. A reflection produces a mirror image of a figure.

• rotation
• translation
• dilation
• reflection

a transformation that changes the size of a figure, but not the shape

• translation
• rotation
• reflection
• dilation

A transformation that “turns” a figure about a fixed point at a given angle and a given direction.

• rotation
• translation
• reflection
• dilation

Given C(2, 9), under which reflection is C'(-2, 9)?

• reflected in the x-axis
• reflected in the y-axis
• reflected in the line x = 2
• reflected in the line y = x

Write a rule for the translation.

•  (x -1, y  + 2)
•  (x -2, y  + 1)
•  (x +2, y  - 1)
• (x +1, y  -  2)

Find K'.

• (4, 1))
• (-1, -4)
• (1, -4)
• (1, 4)

Given C(2, 9), under which reflection is C'(-2, 9)?

• reflected in the x-axis
• reflected in the y-axis
• reflected in the line x = 2
• reflected in the line y = x

Write a rule for the translation.

•  (x -1, y  + 2)
•  (x -2, y  + 1)
•  (x +2, y  - 1)
• (x +1, y  -  2)

Identify the transformation.

• Reflection across y axis
• Reflection across x-axis
• 180 Rotation
• Translation 2 units down

Identify the transformation.

• Reflection across y-axis
• 90 Rotation counter clockwise
• Translation 5 units left, 1 unit up.
• Translation 5 units right, 1 unit down
