Answer:
What is a Scale Factor?
The scale factor is the ratio of the corresponding side lengths in the original figure and the image.
If the image was created by reducing the size of the original figure, then the scale factor is less than 1.
If the image was created by enlarging the size of the original figure, then the scale factor is greater than 1.
The given options for the scale factor are "one half" and "two fourths".
"One half" is equivalent to 0.5.
"Two fourths" is equivalent to 0.5 as well (since 2/4 can be simplified to 1/2, which is 0.5).
Therefore, the scale factor used to create the image is 0.5 or one half, which suggests that the image was created by reducing the size of the original figure by a factor of 0.5.
