Question

What happens when the scale factor is greater than 0 but less than 1?

Answer 1

Then the new image is smaller than the original image.

Explanation:

If the scale factor is less than `1`, then the image formed is going to be smaller than the original image.

For example:

If `triangleABC` is a triangle that has sides `4,2,6` and is reduced to a second triangle, say `triangleA'B'C'`, with a scale factor of `1/2`, then `triangleA'B'C'` will have dimensions of `2,1,3`, with the corresponding sides of `triangleABC`.

Let's look at that with an image:
