Dilations

Given the picture, determine if the dilation is an elargemnent or reduction?

• Enlargement

• Reduction

A scale factor of less than one means...

• that the dilated image will be larger than the pre-image

• that the dilated image will be the same as the pre-image.

• that you need to subtract that amount off of each side.

• that the dilated image will be smaller than the pre-image.

Given the image, determine if the dilation is an enlargement or reduction.
