- 8. Module 8.3 Lesson 3 Examples of Dilations.notebook 8 May 24, 2016 Would you be able to produce a circle as an image from the number of points used in this example? Page 15
- 9. Module 8.3 Lesson 3 Examples of Dilations.notebook 9 May 24, 2016 What's wrong with using these points?
- 10. Module 8.3 Lesson 3 Examples of Dilations.notebook 10 May 24, 2016 What about this image. Does it look like a circle?
- 11. Module 8.3 Lesson 3 Examples of Dilations.notebook 11 May 24, 2016 The number of points to dilate that is enough is as many as are needed to produce a dilated image that looks like the original. For curved figures, like this circle, the more points you dilate the better. The location of the points you choose to dilate is also important.
