Question

Is the enlargement or a reduction? Find the scale factor of the dilation.
Explain

Answer 1

Good evening ,

Answer:

In this case the dilation is a reduction (as you can see the image triangle is smaller than the original triangle)

and also the scale factor = OA’/OA = 2/6 = 1/3

since -1 < 1/3 < 1 then it’s a reduction.

Explanation:

Look at the photo below for more details (notice OA’ and OA).
