Geometric Transformations

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

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

• Translation 6 right and 6 down

• Translation six left and six up

Describe the transformation shown.

• Rotation 90^o clockwise

• 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

Write a rule for the translation.

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

What is the algebraic notation of a figure is Translated 9 units right and 3 units down?

• (x, y) --> (x - 9, y + 3)
• (x, y) --> (x + 9, y - 3)
• (x, y) --> (x + 3, y - 9)
• (x, y) --> (9x, 3y)

The shapes stay congruent when translating, rotating, and reflecting.

• True
• False
