PPT-Medial axis S is a set of n points in the plane

Vor S is the locus of centers of maximum empty disks Vor S is the set of meeting points if the plane is burned uniformly and simultaneously from every site of S Consider the boundary of a convex polygon P as the source of fire The meeting points inside P realize the medial axis.

The elements used to ascertain the symmetry of a molecule quantitatively is called Symmetry elements.. A symmetry element is a geometrical entity such as a line about which a rotation is carried out, a point about which an inversion is carried out or a plane about which a reflection is carried out to generate an equivalent orientation or indistinguishable orientation..
