The statement, "after dilation, the angles in the pre-image are the same as those in the image" is TRUE.
What is Dilation?
A transformation where the size of an original image (pre-image) is enlarged or reduced to the size of a new image (image), is called dilation.
When a pre-image is enlarged, the size is increased by a scale factor to form an image that is larger than the original after dilation. On the other hand, when the pre-image is reduced, the size of the new image (image) is smaller than the original after dilation.
Thus, after dilation, the corresponding sides of the pre-image and the image are proportional to each other while the corresponding angle measures are congruent.
This implies that, after dilation, the angles in the pre-image are the same as those in the image.
Thus, the statement is true.
