Common pictures sizes (in inches) are 4 × 6, 5 × 7, 8 × 10, 9 × 12, 11 × 14, 14 × 18, and 16 × 20.

Are any of these picture sizes similar? Use similarity transformations.

The picture sizes that are similar are __. Dilating the smaller picture size using a scale factor of ___.
results in the larger picture size.

What does your conclusion indicate about resizing pictures?

Because most of the common picture sizes
(select) [are/are not]
similar, when resizing pictures one of two things will occur: the picture will be distorted or part of the picture will need to be cropped out.
