[ noun ] (mathematics) an attribute of a shape; exact correspondence of form on opposite sides of a dividing line or plane

The nuclear dipole effects provide some information on the motions of the hydrogen nuclei , but the symmetry of the **f bond in **f remains in doubt .
There is , then , the possibility that this **f bond is symmetric , although Douglass was unable to determine its symmetry from his x-ray data .
Douglass found **f to be trigonal , Laue symmetry **f , with **f , **f .
The x-ray data did not permit Douglass to determine uniquely the space group , but a negative test for piezoelectricity led him to assume a center of symmetry .
However , the possible absence of a center of symmetry not_only moves the hydrogen_atom off **f , but also allows the oxygen atoms to become nonequivalent , with **f at **f and **f at **f ( space group **f ) , where **f represents the oxygens on one side of the **f layers and **f those on the other side .
[ noun ] balance among the parts of something

The aspects of physical development that catch the judges ' eyes and which rightfully influence their decisions are symmetry and that hallmark of the true champion - superior definition of the muscles .
