Using this Geogebra applet will allow students to explore the concept of geometric dilations.
1. What is the value of k when the figure is a reduction? 2. What is the value of k when the figure is an expansion? 3. Based on this information, what does k represent? 4. What happens to the figure when k = 1? Why does this happen? 5. How can we find the value of k if we are only given the lengths of the sides of the figure?
