Exploring the reflection
Reflect the shape below through the x-axis, y-axis, blue line (y=x), and purple line (y=-x) . Then answer the questions below in your Math notebook.
1) What happens to coordinates in a reflection through the x-axis? Write your conclusions.
2) What happens to coordinates in a reflection through the y-axis? Write your conclusions.
3) What happens to coordinates in a reflection through the blue line (y=x) ? Write your conclusions.
4) What happens to coordinates in a reflection through the purple line. (y=-x) ? Write your conclusions.
5) Draw these reflections in your Math notebook. Paint each one with different colors and the original triangle uses black. Then check in Geogebra if your reflections are correct. In the next class you will do one alone on a separate sheet, so pay attention, do it diligently, and ask the teacher if you have any questions.
