Perform a Dilation

State the coordinates of the image of point C after a dilation with a scale factor of 1/2 and center point P.

• (-6, 1)

• (-3, -2)

• (1, -6)

• (-2, -3)

What scale factor was used to produce the green image? (the blue triangle was the original image)

• 2

• -2

• ¹/₂

• 1

Does the image show a Dilation?

• Yes

• No

What is the scale factor to go from triangle ABC to triangle A'B'C'?

• k = 2

• k = 1/2

• Center (0,0)

• (0,2)

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

• an enlargement

• a reduction

• a scale factor

• bigger

If the scale factor is greater than one in a dilation, the new figure will be

• a reduction

• an enlargement

• a scale

• not proportional

A dilation produces a similar figure

• True

• False

Does the image show a dilation?

• Yes

• No

What two things do you need to know in order to perform a Dilation?

• Location of the Center

• The Pre-Image

• The Scale Factor

• The type of shape
