Geometric Transformations Diagnostic

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

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

• Translation and dilation

• Translation only

• Dilation only

• Rotation and reflection

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

If blue is the pre-image and green is the image, the scale of reduction is?

• 1/2

• 1/3

• 3

• 2

Describe the transformation shown

• Rotation of 270^o counter clockwise

• Translation right one unit and up one unit

• Dilation by a scale of 2

• Dilation by a scale of 1/2

Identify the transformation.

• Reflection across y axis

• Reflection across x-axis

• 180 Rotation

• Translation 2 units down

• 1
• 2
• 3
• 4

The dashed figure is the image of the solid figure.  What is the Algebraic Notation for the Translation?

• (x, y) --> (x - 7, y + 4)

• (x, y) --> (x + 7, y - 4)

• (x, y) --> (x + 4, y - 7)

• (x, y) --> (7x, 4y)
