Dilation of a Segment
- Azucena Overman
Blue point A is the "point of dilation". Red segment BC is the pre-image and can be moved around. Set the length of BC with the red slider. Green segment B'C' is the image after using the dilation factor on the pre-image around point A. The dilation factor can be set with the green slider.
Compare the length of B'C' to the length of BC with different Dilation Factors. What relationship do you see? Compare the distance of the original point B to point A with the distance from B' to point A using different dilation factors. What relationship do you see?
