Understand similarity in terms of similarity transformations1. Verify experimentally the properties of dilations given by a center and a scale factor:a. A dilation takes a line not passing through the center of the dilation to a parallel line, and leaves a line passing through the center unchanged.b. The dilation of a line segment is longer or shorter in the ratio given by the scale factor.

Long Term Learning Target:
Given a center and scale factor, I can verify that dilating a figure: leaves any lines passing through the center of the figure unchanged; takes a line not passing through the figure’s center to a parallel line; makes dilations of line segments longer or shorter in the ratio given by the scale factor.
