6.1 dilation

Dilate a 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)

Choose the correct scale factor:

• 2

• 3

• 1/3

• 1/2

A dilation is which of the following:

A dilation produces a similar figure.

• True

• False

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

• True
• False

When a dilation has a scale factor greater than one, the dilation is an enlargement.

• True
• False
