G-SRT.A.1. Verify experimentally the properties of dilations given by a center and a scale factor:

    G-SRT.A.1.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.

    G-SRT.A.1.b. The dilation of a line segment is longer or shorter in the ratio given by the scale factor.
