geometry

 translation
 find the translation of a geometric object with respect to a directed segment

 Calling Sequence translation(Q, obj, AB)

Parameters

 Q - the name of the object to be created obj - geometric object AB - directed segment

Description

 • Let AB be a directed line segment in the plane S. By the translation $T\left(\mathrm{AB}\right)$ we mean the transformation of S onto itself which carries each point P of the plane into the point P1 of the plane such that the directed line segment PP1 is equal and parallel to the directed segment AB.
 • The directed segment AB is called the vector of the translation.
 • For a detailed description of Q (the object created), use the routine detail (i.e., detail(Q))
 • The command with(geometry,translation) allows the use of the abbreviated form of this command.
