Answer:
- point P is a midpoint of segment AA'
- XY is perpendicular to AA'
Step-by-step explanation:
Consider given line XY and point A (see attached diagram for details).
To reflect point A over a line XY, you have to draw perpendicular line to the line XY passing through tha point A. This line intersects XT at point P. Then plot point A' such that A' lies on the line AP and AP=PA'.
Therefore,
- point P is a midpoint of segment AA'
- XY is perpendicular to AA'
