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 3 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.[br]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.[br]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.[br]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.[br]5) What does a dilation factor of 1 do?[br]6) What does the dilation factor greater than 1 do?[br]7) What does then dilation factor less than 1 do?
