Question

how would you explain to a classmate what it means when the scale factor of a dilation is less than 1? equal to 1? greater than 1?

Explanation:

When the scale factor of a dilation is less than 1, the image is a reduction of the pre - image, meaning it is smaller. When it is equal to 1, the image and pre - image are congruent as there is no size change. When it is greater than 1, the image is an enlargement of the pre - image, making it larger.

Answer:

When the scale factor of a dilation is less than 1, the image is a reduction of the pre - image. When it is equal to 1, the image and pre - image are congruent. When it is greater than 1, the image is an enlargement of the pre - image.
