Copy of Dilation Introduction: Transformers!
Explore this applet to see how the center of dilation and the scale factor affect the image.
1) Set the x-coordinate and y-coordinate of the center to (0, 0) and the scale factor to 0. Explore the way the segments change (keep an eye on the coordinates) as you increase the scale factor.
2) When does the image of the transformer gets larger?
3) When does it stay the same?
4) When is the image smaller than the pre-image?
5) What do you notice with the pre-image and image points as you toggle the center of dilation?
6) What happens to the image when the scale factor is set at a negative value?
