find the reflection of a geometric object with respect to a given point or line
reflection(Q, P, c)
the name of the object to be created
point or line
Let c be a fixed point in the plane. By the reflection (or half-turn) R⁡c in point c we mean the transformation of the plane S onto itself which carries each point P of the plane into the point Q of the plane such that c is the midpoint of PQ. Point c is called the center of the reflection.
Let c be a fixed line in the plane. By the reflection R⁡c about line c we mean the transformation of the plane S onto itself which carries each point P of the plane into the point Q of the plane such that c goes through the midpoint of PQ and is perpendicular to PQ.
For a detailed description of the object created Q, use the routine detail (i.e., detail(Q))
The command with(geometry,reflection) allows the use of the abbreviated form of this command.

reflection of a line with respect to a line
reflection of a circle with respect to a line
