- 7. Geometry Lesson 1 Examples of Dilations.notebook 7 October 20, 2016 What about this image. Does it look like a circle?
- 8. Geometry Lesson 1 Examples of Dilations.notebook 8 October 20, 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.
