Dilation Properties

➢ Common Core Standard HSG.SRT.A.1 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. ➢ Learning Targets What you will learn: Dilations have specific effects on lines and line segments. How you will know you’ve learned it: • You can predict the slope of the image of a line or a line segment, after dilation. • You can predict the length of a line segment, after dilation. • You can justify your prediction using the definition of a dilation with a given center and scale factor.
