Which transformation moves a geometric pre-image right, left, up or down?

• Translation

• Rotation

• Reflection

• Dilation

Which transformation flips an image across either the x or y axis?

• Translation

• Rotation

• Reflection

• Dilation

Which transformation pivots a pre-image around the origin either clockwise or counter clockwise?

• Translation

• Rotation

• Reflection

• Dilation

Which transformation preserves the size of a pre-image? (Chose the best answer)

• Rotation

• Translation

• Reflection and dilation

• Reflection, rotation, and translation

Describe the rotation shown.

• Rotation 180^o

• Rotation 90^o clockwise

• Rotation 90^o counter clockwise

• Rotation 270^o clockwise

If blue is the pre-image, describe the transformation

• Rotation 180^o

• Dilation by a factor of 1/2

• Translation 6 right and 6 down

• Translation six left and six up

Describe the transformation shown.

• Rotation 90^o clockwise

• Dilation by a factor of 3

• Translation 2 units down

• Reflection across the x axis.

Describe the transformation shown if the image on the left is the pre-image.

• Reflection across the y axis

• Translation 4 units right

• Rotation 90^o clockwise

• Dilation by a factor of 2

Describe the transformation shown

• Reflection across the x axis.

• Translation down 6 and left 1

• Dilation by a factor of 2/3

• Rotation of 180^o

A turn is also called a ___________.

• Translation
