Dilations 8.3A & C

When dilating a figure what kind of math are you using?

• Division

• Addition

• Multiplication

• Square Root

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.

Which best describes an enlargement?

• Stretches the original image

• Shrinks the original image

Which best describes a reduction?

• Stretches the original image

• Shrinks the original image
