Question

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

Answer 1

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.

`9/3=3`

Therefore, the scale factor of the dilated image is 3.
