What are the important pieces of information given for a dilation?

In a dilation, the important pieces of information include the center of dilation, which is the fixed point around which the dilation occurs, and the scale factor, which determines how much the figure is enlarged or reduced. The scale factor indicates the ratio of the distance from the center of dilation to a point on the image compared to the distance from the center to the corresponding point on the original figure. Additionally, the dimensions of the original figure and the coordinates of its vertices are essential for accurately performing the dilation.
