point symmetry meaning in Hindi

Examples

1. Since each face has point symmetry, a parallelepiped is a zonohedron.
2. Most attacks secretly employ the point symmetry group of the system of geodesic equations.
3. For example, it arises as the point symmetry group of a certain ordinary differential equation.
4. Also the whole parallelepiped has point symmetry " C i " ( see also triclinic ).
5. Since each of its faces has point symmetry ( equivalently, 180?rotational symmetry ), the truncated icosidodecahedron is a zonohedron.
6. There are four basic isometries of 4-dimensional point symmetry : reflection symmetry, rotational symmetry, rotoreflection, and double rotation.
7. A common subunits puts two rings of six subunits side by side along the sixfold axis ( or 2-6-point symmetry ).
8. For restricted versions of this problem, there exist polynomial time algorithms that solve the corresponding optimization problems for a few point symmetries in 2D.
9. In these cases the iron-pyrite FeS 2, where sulfur ions occupy lattice site of point symmetry group " C " 3.
10. Roughly speaking, a Lie point symmetry of a system is a local group of transformations that maps every solution of the system to another solution of the same system.
