Answer the following questions in your notebook:
1. Slide the purple slider. How does the scale factor effect Δ ABC? Be sure to examine what happens when k > 1 and when k is between 0 and 1.
2. Slide k to 2 and find each ratio in simplest form:
A/B/: AB
B/C/: BC
A/C/: AC
What do you observe?
3. Slide k to ½ and find each ratio in simplest form:
A/B/: AB
B/C/: BC
A/C/: AC
What do you observe?
4. Based on your observations, make a conjecture about the relationship between the length of the image of a segment, the length of the pre-image of the segment, and the scale factor.
