Answer:

1. A figure has symmetry with respect to a point P if for every point Q of the figure a partner point Q' exists such that P is the midpoint of QQ’.

2. A figure has symmetry with respect to a plane X if for every point K of the figure a partner point K' exists such that X is the perpendicular bisector of KK’.

3. A figure has symmetry with respect to a line m if for every point P of the figure a partner point P' exists such that m is the perpendicular bisector  of PP’.
