  1. Geometry 4-4 Dilations

  2. Goals • Identify and perform dilations. • Solve real-life problems involving scale factors and dilations.

  3. 4-4 Dilations A dilation is a transformation in which a figure is enlarged or reduced with respect to a fixed point.

  4. 4-4 Dilations A dilation is a transformation in which a figure is enlarged or reduced with respect to a fixed point C called the center of dilation and a scale factor k, which is the ratio of the lengths of the corresponding sides of the image and the preimage.
