Study Notes
Reflection Over Axes
- Reflection across the x-axis transforms a point (x, y) to (x, -y).
- Reflection across the y-axis changes a point (x, y) to (-x, y).
Examples of Reflection Across the X-axis
- Reflecting (2,-3) results in (2,3).
- Reflecting (5,7) gives (5,-7).
- Reflecting (7,-8) yields (7,8).
- Reflecting (-1,7) transforms to (-1,-7).
- Reflecting (3,-7) leads to (3,7).
- Reflecting (-2,-7) results in (-2,7).
- Reflecting (-6,7) gives (-6,-7).
- Reflecting (10,14) transforms to (10,-14).
Examples of Reflection Across the Y-axis
- Reflecting (-3,2) results in (3,2).
- Reflecting (2,-3) over the y-axis yields (-2,-3).
- Reflecting (-2,-5) leads to (2,-5).
- Reflecting (-5,-5) gives (5,-5).
- Reflecting (7,10) results in (-10,7).
- Reflecting (7,8) transforms to (-7,8).
- Reflecting (3,-7) leads to (-3,-7).
- Reflecting (15,-2) gives (-15,-2).
- Reflecting (-10,-11) results in (10,-11).
- Reflecting (-5,3) transforms to (5,3).
