Transformation Reflect and Rotate

Which series of transformations were performed in the figure?

• Translation 5 units down, reflection over the y-axis

• Reflection over the x-axis, translation 6 units right

• Rotation 90^o clockwise, reflection over the x-axis

• Rotation 180^o clockwise, reflection over the y-axis

Describe a sequence of transformations that maps figure A onto figure B.

• translation 4 units right followed by a reflection across the x-axis

• reflection across the x-axis followed by a reflection across the y-axis

• reflection across the y-axis followed by a translation 6 units down

• 90° counter-clockwise rotation about the Origin followed by a reflection across the y-axis

Which answer shows a reflection across the y-axis?

• a

• b

• c

• d

How many degrees was the figure rotated?

• 180 degrees

• 270 degrees counterclockwise

The rule for reflection over the y-axis is  
(x, y) --> _

• (-x, y)

• (x, -y)

• (y, x)

• (-y, x)

The rule for rotation of 180 degrees is  
(x, y) --> _

• (-y, x)

• (-x, -y)

• (y, -x)

• (-y, -x)

How many degrees was the figure rotated?

• 90 degrees counterclockwise 

• 180 degrees

• 270 counterclockwise
