Exploring Dilations
In this activity, you will be observing a dilation about the origin. Use the "Scale Factor" slider to dilate the original pre-image and try and answer the following questions on the worksheet provided.
1) Describe what happens if the scale factor is less than 1.
2) Describe what happens if the scale factor is 1.
3) Describe what happens if the scale factor is greater than 1.
4) Move the scale factor to 3. Write down the original pre-image coordinates, and the dilation image coordinates. What do you notice when you compare the original coordinates to the dilation's coordinates?
5) Move the scale factor to 0.5. Write down the original pre-image coordinates, and the dilation image coordinates. What do you notice when you compare the original coordinates to the dilation's coordinates?
