Is a dilation a rigid motion?
Pg 587

3. If the scale factor is < 1, the dilation is called a reduction.
If the scale factor is > 1, the dilation is called an enlargement.
What are the scale factors for each of these dilations?
Pg 588

4. What is the scale factor?
What is the center of dilation?

5. Draw the dilation with the scale factor n=2 and the center of dilation M.Z P G

6. A
Perform the dilation with a scale factor ¼ and a center of dilation at C. S C

7. When looking through a telescope, an astronomer measures the diameter of the moon to be 2.2 cm. He knows that the telescope shows 1000 miles in each centimeter.
What is the scale factor?
What is the diameter of the moon?
