The solid line figure is a dilation of the dashed line figure the labeled point is the center of the dilation find the scale factor for each dilation

The length of the base of the triangle of the dilation is equal to 3 + 6 = 9 units.
The length of the base of the triangle of dashed line triangle is equal to 3 units.
Divide the length of the dilated side to the orignal figure.
[tex]9\div3=3[/tex]Therefore, the scale factor of the dilated image is 3.
