Question

in geometry, the scale factor is a number that is select by each side length of the original image to get the copy.
if the scale factor is a number greater than 1, then the scaled figure will be select .
if the scale factor is 1 exactly, then the scaled figure will be select .
if the scale factor is a number less than 1, then the scaled figure will be select .

Explanation:

1. The scale factor defines the operation used to transform the original figure's side lengths to create a scaled copy.
2. A scale factor >1 increases all side lengths, making the figure larger.
3. A scale factor =1 leaves all side lengths unchanged, so the figure matches the original.
4. A scale factor <1 decreases all side lengths, making the figure smaller.

Answer:

1. multiplied
2. an enlargement (larger than the original)
3. congruent to the original (same size and shape)
4. a reduction (smaller than the original)
