[MII.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.
- Dilation
A transformation that moves each point along the ray through the point emanating from a fixed center, and multiplies distances from the center by a common scale factor.
