• 90^o clockwise rotation
• 90^o counter clockwise rotation
• Reflection across the y-axis
• Reflection across the x-axis

Identify the transformation from C to D.

• 90^o Clockwise Rotation
• 180^o Rotation
• 270^o Clockwise Rotation
• 360^o Rotation

If you were to rotate ABCD 90° counterclockwise about the origin, what would the coordinate of A' be?

• (-5, 5)
• (-3, 5)
• (-5, 3)
• (-3, 3)

Identify the transformation from ABC to A'B'C'.

• Reflection across the x-axis
• Reflection across the y-axis
• 90^o clockwise rotation
• 90^o counterclockwise rotation

What is the sequence of transformations for the image given? 

• Reflect over x-axis,

  then translate

  (x,y)--> (x+8,y)

• Reflect over x-axis then translate

  (x,y)-->(x+6, y)

• Reflect over y-axis then translate

  (x,y)-->(x+1, y+1)

• Reflect over y-axis, then translate

  (x,y)--> (y-4,x+5)

A dilation with a scale factor of 2 is a reduction. 

• True
• False

A dilation with a scale factor of 1/3 is a reduction. 

• True 
• False

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

Write a rule for the translation.

• (x,y)--> (x -1, y  + 2)

•  (x,y)-->(x -2, y  + 1)

•  (x,y)-->(x +2, y  - 1)

• (x,y) -->(x +1, y  -  2)

• 0
• 1
• 2
• 4
