Applying the Properties of Dilation and Similarity

What is the scale factor of the dilation of ABC to XYZ?

• 2

• 3

Tell whether the two figures are congruent or similar.

• Congruent, because their sides are the same.

• Congruent, because their sides are proportional.

• Similar, because their sides are the same.

• Similar, because their sides are proportional.

• They are not congruent or similar.

Tell whether the two figures are congruent or similar.

• Congruent, because their sides are the same.

• Congruent, because their sides are proportional.

• Similar, because their sides are the same.

• Similar, because their sides are proportional.

• They are neither congruent or similar.

Triangle ABC is dilated using a scale factor of 1/2 with the origin as the center of dilation. What are the new coordinates of point A'?

• (-3, 3)

• (-12, 12)

• (-2, 2)

Given that Triangle BAC is similar to Triangle EDF. Find the length of ED.

• 6

Does the image show a Dilation?

• Yes

• No

A dilation is which of the following: 

• An enlargement

• A reduction

• Either an enlargement or a reduction

• Neither an enlargement or a reduction

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

• an enlargement

• a reduction

• a scale factor

• bigger

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

• reduction

• enlargement

• scale

• not proportional
