Question

The dashed triangle is the image of the solid triangle. The center of dilation is (−4, −4) .

What is the scale factor used to create the dilation?

Answer 1

The horizontal leg has length 6 in the dashed triangle and 2 in the solid one.

The vertical leg has length 9 in the dashed triangle and 3 in the solid one.

So, all lengths have been divided by 3, implying that the scale factor was 1/3.

Answer 2

the scale factor is 3
