CG 7 Dilations
- Ms. Andres
Dilating a Triangle
1. Compare the lengths of corresponding sides. What do you notice? 2. Compare the measures of corresponding angles. What do you notice?
Try the dilation tool, using point X as your center of dilation. Experiment with scale factors between 0 and 1 as well as greater than 1. See what effect moving point X has on the image.
What effect did using a scale factor between 0 and 1 have on the image?
What effect did using a scale factor greater than 1 have on the image?
Move point X to the origin. What ordered pair rule maps the pre-image onto the image? Use k to represent your chosen scale factor.
