Quiz 7 & 9 Review

A dilation produces a similar figure

• True

• False

When the scale factor of a dilation is less than one, the dilation is a reduction (gets smaller).

• True

• False

An image is dilated at a scale factor of 1.5. This means the dilation is an enlargement and the dilated image will be bigger.

• True

• False

Choose the correct scale factor:

• 2
• 3
• 1/3
• 1/2

Dilate Point B by a scale factor of 3:

• (12,0)
• (12,12)
• (4,3)
• (0,12)

Does the image show a dilation?

• Yes
• No

A dilation produces a congruent figure

• True

• False

Dilate the figure by a scale factor of 3 with the origin as the center of dilation. What are the coordinates of the image?
A(3,3) B(6,6) C(9,3)

• A'(9,9) B'(18,18) C'(27,9)
• A'(6,6) B'(9,9) C'(12,6)
• A'(0,0) B'(3,3) C'(6,0)
• A'(1,1) B'(2,2) C'(3,1)

5.) What is the scale factor of the dilation from A to B ?

• 1/4

• 1/2

• 1

• 2

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
