Transformations: Reflect about a line

This activity will explore what happens when you reflect a polygon over three specific lines.

1. Before exploring with the activity above record what you think will happen to the coordinates when you reflect a polygon over x=0, y=0, and y=x. 2. Using the check boxes, show and hide polygon reflections across each given line. 3. How did the coordinates of each point change when reflecting over x=0? 4. How did the coordinates of each point change when reflecting over y=0? 5. How did the coordinates of each point change when reflecting over y=0? 6. Write a general rule for each relfection using coordinate notation.
