Drag point O to change the center of the dilation. Drag points A, B, or C to change the pre-image. To change the dilation factor, enter a number between 0 and 5 and hit enter.
1) Move the center of dilation point O to point A. Change the dilation factor to any number between 0 & 3 and see what happens.
2) Move the center of dilation point O to point B. Change the dilation factor to any number between 0 & 3 and see what happens.
3) Move the center of dilation point O to point C. Change the dilation factor to any number between 0 & 3 and see what happens.
4) Move the center of dilation point O to the center of the pre-image. Change the dilation factor to any number between 0 & 3 and see what happens.
5) What does a dilation factor of 1 do?
6) What does the dilation factor greater than 1 do?
7) What does then dilation factor less than 1 do?
