Dilations

> 1 Enlargement

> 0 & < 1 Reduction

=0 Makes it a point

Negative: Reflection through Point (Center of Dilation)

Set up the proportions to determine if they are similar

Set up the proportions to determine if they are similar

 $\frac{24}{20}=\frac{18}{15}=\frac{12}{10}$   $\frac{6}{5}=\frac{6}{5}=\frac{6}{5}$  

 $\frac{25}{10}=\frac{x}{6}$  -->  $\frac{25\cdot6}{10}=x$  
 $\frac{x}{25}=\frac{6}{10}$  -->  $x=\frac{6\cdot25}{10}$  
Make sure you look at CORRESPONDING sides
