Exploring Reflections with Intersecting Lines
- Author:
- Marybeth Gakos, Auston B Cron
Click on each of the Reflection boxes separately, then together to learn how the letter F behaves when reflected in two intersecting lines.
Click on the grid button to see the coordinate grid. Record the coordinates of Point D for the preimage, then the image after each reflection.
Describe one transformation that would transform the preimage to the image after two reflections.
Move the lines so that they are perpendicular. Record the coordinates for Point D for the final image. Does your description still apply?
Answer the remaining questions on the worksheet.
