Exploring Dilation
Exploring dilation:
In this activity you will explore how the image enlarges or shrinks
Follow the steps and the instructions given for each question and write down the properties of dilation.
1) When 0< K < 1
slide K to a any value between 0 and 1.For example =0.5. Compare the preimage and the iamge. What happens to the image?
2) When K=1
Slide K=1 . Compare the pre image and the image.What do you notice?
3) When K >1
Slide k to any value greater than 1 .For example k=1.5. Compare the pre image and the image.What happens to the image?
4) Finding the scale factor K
Slide K to any value. Find K, What do you notice about them all?
5) Finding scale factor, K, using the ordered pairs
Slide K=2 What are the coordinates of A, B, A' and B'. How can you find the scale factor using the ordered pairs?
