Answer:
-
- Enlargement.
Step-by-step explanation:
It is important to remember that a dilation is defined as a transformation that does not change the shape, but the size.
If the image is larger than the pre-image, then the dilation is called "Enlargement".
If the image is smaller than the pre-image, then the dilatation is called "Reduction".
Observe the image attached.
According to the information provided in the exercise, the dashed figure is the image. Notice that it is larger than the original figure; therefore, you can classify the dilatation as an Enlargement.
In order to find the scale factor, you can divide the x-coordinate of a vertex of the image by the x-coordinate of the corresponding vertex of the pre-image. Then, this is:
