### 5.

Create an image by applying a dilation with point

Decide if the two given figures are similar. Include as many details as possible about the transformations used to justify the similarity. For example, if a dilation is used, state details such as the center of the dilation and the scale factor.

Based on the given image and pre-image, determine the transformation that occurred. Justify the transformation occurred by showing evidence of some kind.

(For example, if the transformation was a reflection, show the line of reflection exists and prove it is the perpendicular bisector of all segments that connect corresponding points from the image and pre-image. Provide similar evidence for rotations, translations, and dilations.)
