A reflection over line l fixes every point parallel to l, while a 180° rotation about P fixes only the center point P.

A reflection over line l fixes every point on l, while a 180° rotation about P also fixes every point the same distance from P.

A reflection over line l fixes only the point where P lies on l, while a 180° rotation about P fixes every point on line l.

A reflection over line l fixes every point on l, while a 180° rotation about P fixes only the center point P.
