Description
In the previous lesson, students used transformations to prove that all parabolas with the same distance between the focus and directrix are congruent. In the process, they made a connection between geometry, coordinate geometry, transformations, equations, and functions. In this lesson, students explore how dilation can be applied to prove that all parabolas are similar.
