When the scale factor of a dilation is less than one, the dilation is a...

• Reduction

• Enlargement

A dilation produces a similar figure

• True

• False

Dilate Point C by a scale factor of 3:

• (12,0)

• (12,12)

• (1, 2/3)

• (9, 6)

Does the image show a Dilation and what is the scale factor?

• Yes; k = 2

• Yes; k = 1/2

• No, it's a translation.

• No, it's a reflection.

(x, y) -> (2x, 2y) 
What is the coefficient 2 mean?

• plot 2 to the right and 2 up
• scale factor is 2 creating a new figure half the size
• scale factor is 2 making a figure twice the 
  original
• I don't understand this question : ( 

The __________ is the ratio of a length of the new figure to the corresponding length on the original figure.

• reduction
• enlargement
• scale factor
• center of dilation

If a dilation produces a congruent figure, then the scale factor was equal to _____.

• 1/2
• 2
• 10
• 1

If the scale factor is less than one, the new figure will be

• larger

• smaller
