Dilation Properties

This is a demonstration of the properties of the non-rigid transformation known as a dilation.
Preimage = Blue triangle Image = Red triangle What do you notice about the effects of a scale factor which is:
  • equal to 0?
  • greater than 0 but less than 1?
  • equal to 1?
  • greater than 1?
What do you observe about the relationship:
  • between the scale factor and the distances of the preimage and image vertices from the center of dilation?
  • between the scale factor and the side lengths of the preimage and image?
