  what is a polyhedron definition	A polyhedron is said to be convex if its surface (comprising its faces, edges and vertices) does not intersect itself and the line segment joining any two points of the polyhedron is contained in the interior or surface. A polyhedron is a 3-dimensional example of the more general polytope in any number of dimensions. Polyhedra with congruent regular faces of six or more sides are all non-convex, because the vertex of three regular hexagons defines a plane. The total number of convex polyhedra with equal regular faces is thus ten, comprising the five Platonic solids and the five non-uniform deltahedra.	0.0
  what can you carry in hand luggage on easyjet	Each passenger who pays for a hold bag can take up to 20kg of luggage. This weight allowance applies to the passenger rather than to the bag so purchasing extra bags is possible but will not increase the weight allowance.	0.0
  what is dynamic segmentation in gis	The result of the dynamic segmentation process is a dynamic feature class known as a route event source. A route event source can serve as the data source of a feature layer in ArcMap. For the most part, a dynamic feature layer behaves like any other feature layer. Event locating errors. The dynamic segmentation process creates a shape for each row in the input route event table. In some cases, however, the shape of the event feature might be empty. This happens when there is a reason that the event can't be properly located.	0.0
