Example 1

Is the following transformation a dilation? Justify your answer using the properties of dilations.
  1. Verify that shape, orientation, and angles have been preserved from the preimage to the image.
  2. Verify that the corresponding sides are parallel.
  3. Verify that the distances of the corresponding sides have changed by a common scale factor, .
  4. Verify that corresponding vertices are collinear with the center of dilation, .
  5. Draw conclusions.
