Exploring Reflections
Instructions
- Move the "mirror line", which we call the [b]Line of Reflection[/b] in our class, to the appropriate location to answer the questions below.
1. Line of Reflection: Y-axis
What happens to the coordinates of the vertices of the shape after a reflection about the y-axis?
2. Generalize your hypothesis into a rule that will illustrate the changes in the coordinates.
Reflection about the y-axis:[br](x, y) [math]\longrightarrow[/math]
3. Line of Reflection: X-axis
What happens to the coordinates of the vertices of the shape after a reflection about the x-axis?
4. Generalize your hypothesis into a rule that will illustrate the changes in the coordinates.
Reflection about the x-axis:[br](x, y) [math]\longrightarrow[/math]
5. Line of Reflection: y = x
What happens to the coordinates of the vertices of the shape after a reflection about the line y=x?
6. Generalize your hypothesis into a rule that will illustrate the changes in the coordinates.
Reflection about the line y = x.[br](x, y) [math]\longrightarrow[/math]
7. Line of Reflection: y = -x
What happens to the coordinates of the vertices of the shape after a reflection about the line y=-x?
8. Generalize your hypothesis into a rule that will illustrate the changes in the coordinates.
Reflection about the line y = -x.[br](x, y) [math]\longrightarrow[/math]
