Answer 16

Define enlargement and reduction.

A dilation is a type of dilation where the value of the scale factor is greater than 0. An enlargement is a type of dilation where the value of the scale factor is less than 0.

A dilation is a type of dilation where the absolute value of the scale factor is greater than 1. An enlargement is a type of dilation where the absolute value of the scale factor is between 0 and 1.

An enlargement is a type of dilation where the value of the scale factor is greater than 0. A reduction is a type of dilation where the value of the scale factor is less than 0.

An enlargement is a type of dilation where the absolute value of the scale factor is greater than 1. A reduction is a type of dilation where the absolute value of the scale factor is between 0 and 1.
