What is true about the dilation? On a coordinate plane, the triangle image has points (0, 0), (2, 4), (4, 0). The triangle pre-image has points (0, 0), (4, 8), (8, 0). It is a reduction with a scale factor between 0 and 1. It is a reduction with a scale factor greater than 1. It is an enlargement with a scale factor between 0 and 1. It is an enlargement with a scale factor greater than 1.
Answers
In dilation, to obtain the new dimensions of the image you must multiply the dimensions of the original image by a number called "Scale factor". ... When the scale factor is greater than 1 it is an enlargement and when this is between 0 and 1, it is a reduction.

Corrected question:
What is true about dilation? On a coordinate plane, the triangle image has points (0, 0), (2, 4), (4, 0). The triangle pre-image has points (0, 0), (4, 8), (8, 0).
A. It is a reduction with a scale factor between 0 and 1.
B. It is a reduction with a scale factor greater than 1.
C. It is an enlargement with a scale factor between 0 and 1.
D. It is an enlargement with a scale factor greater than 1.
Corrected answer:
The dilation is a reduction with a scale factor between 0 and 1. (Option A)
- A dilation is a reduction on a coordinate plane if the scale factor is between 0 and 1.
- If a dilation with a scale factor of half on this square, it should be a reduction because half is between 0 and 1.
- It creates a smaller image and an enlargement image.
- It is a dilation that creates a larger image.
- So, if the scale factor is between 0 and 1 the image is a reduction and if the scale factor is greater than 1, the image is an enlargement image.
