If the scale factor is greater than 1, the dilation is...

• an enlargement

• a rotation

• a translation

• a reduction

A reduction will occur when...

• the scale factor is 1.

• the scale factor is greater than 1.

• the scale factor is between 0 and 1.

• the scale factor is negative.

Find the scale factor of the enlargement from A to C.

(A is the original image and C is the new image)

• 2

• 0.5

• 3

• 4

Find the scale factor of the reduction from B to A.

(B is the original image and A is the new image).

• 2

• 0.5

• 1.5

• 3

Find the scale factor of the enlargement from A to C.

(A is the original image and C is the new image).

• 0.5

• 3
