This paper gives distributional properties of geometrical characterist
ics of a Voronoi tessellation generated by a stationary Poisson point
process. The considerations are based on a well-known formula given by
[10] describing size and shape of a cell of the Delaunay tessellation
and on the close connection between Delaunay and Voronoi tessellation
. Several results are given for the two-dimensional case, but the main
part is the investigation of the three-dimensional case. They include
the density functions of the angles perpendicular to the ''typical''
edge, spanned by two neighbouring Poisson points and that spanned by t
wo neighbouring faces, the angle between two edges emanating from the
''typical'' vertex, the distance of two neighbouring Poisson points, t
he angle between two edges emanating from the ''typical'' vertex of th
e Poisson Voronoi tessellation and some others. These density function
s are given partly explicitely and partly in integral form.
