# Exploring Dilation

## Dilation

Follow the steps to explore a dilation with the applet below.

__Step 1:__Use the Dilate tool to dilate Triangle ABC. Center the dilation at point D and use a scale factor of your choice.__Step 2:__Using the move tool, change the position of the center of dilation, point D. Consider the following questions: 1) What happens to the triangles as the center of dilation moves? 2) Why does it look like the triangle is translated after the dilation? 3) Where would the point of dilation need to be to prevent changing the position of Triangle ABC?## Finding Center of Dilation

In the applet below, triangle ABC has been dilated to construct triangle A'B'C'. Use the tools given to complete the following tasks.
1) Develop a strategy for finding the center of dilation. (Hint: think about strategies used to find defining information in other transformations).
2) Verify that Triangle ABC is

*similar*to Triangle A'B'C'. 3) Find the scale factor of the dilation.## Finding center of Dilation
