  1. Lesson 7.6 Dilations Pages 393 - 395

  2. What is a dilation? A dilation is a transformation with center C and scale factor k that maps each point P onto an image point P’. Two Types of Dilations – • Reduction – the image figure is smaller than the original figure • Enlargement – the image figure is larger than the original figure

  3. Tell whether the dilation is a reduction or an enlargement. A’ A A A’ D’ D C C B’ B B B’

  4. Find the scale factor of the dilation.Hint: scale factor for enlargements >1 scale factor for reductions between 0 and 1 C C 3 2 B’ B B B’ 5 5

  5. Use a proportion to find the missing length. 2 x 35 x C C 8 24 20 40
