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.

Note how changing the scale factor affects the purple image of the original orange triangle.[br][br]1) How does the image compare to the pre-image if you use a dilation factor greater than 1?[br][br]2) How does the image compare to the pre-image if you use a dilation factor equal to 1?[br][br]3) How does the image compare to the pre-image if you use a dilation factor between 0 and 1?[br]
