Draw the image of AABC in Figure 8.8 for the magnification with center X and scale factor 2. 2. Draw the image of AABC in Figure 8.8 for the magnification with center Y and scale factor 1/2. 3. Copy the figure in Figure 8.9. Draw the image of AABC for the following: a. The magnification with center O and scale factor 2. b. The magnification with center A and scale factor 3. 4. Copy the figure in Figure 8.10. Draw the image of square ABCD for the following: a. The magnification with center O and scale factor 2. b. The magnification with center P and scale factor 3. c. The magnification with center Q and scale factor 1/2. 5. The center of the magnification is point O in Figure 8.11. Com- plete the following: a. For a scale factor of 2, the image of K is b. For a scale factor of 2, the image of IJKL is c. For a scale factor of 3, the image of IJKL is d. For a scale factor of 1/2, the image of H is. e. For a scale factor of 1/2, the image of EFGH is f. For a scale factor of 1/3, the image of ABCD is 6. For the figures in Figure 8.12, find a center O and a scale factor k such that the magnification with center 0 and scale factor k maps the small F to the large F.
