In Euclidean geometry, an orthodiagonal quadrilateral is a quadrilateral in which the diagonals cross at right angles. In other words, it is a four-sided figure in which the line segments between non-adjacent vertices are orthogonal (perpendicular) to each other.
A pentagonal antiprismatic prism or pentagonal antiduoprism is a convex uniform 4-polytope. It is formed as two parallel pentagonal antiprisms connected by cubes and triangular prisms. The symmetry of a pentagonal antiprismatic prism is [10,2 +,2], order 40. It has 20 triangle, 20 square and 4 pentagonal faces. It has 50 edges, and 20 vertices.
Coxeter, Longuet-Higgins & Miller (1954) define uniform polyhedra to be vertex-transitive polyhedra with regular faces. They define a polyhedron to be a finite set of polygons such that each side of a polygon is a side of just one other polygon, such that no non-empty proper subset of the polygons has the same property.
An oblique prism is a prism in which the joining edges and faces are not perpendicular to the base faces. Example: a parallelepiped is an oblique prism whose base is a parallelogram, or equivalently a polyhedron with six parallelogram faces. Right Prism. A right prism is a prism in which the joining edges and faces are perpendicular to the base ...

Legal experts believe the unknown female celebrity tied to the Jay-Z and Sean "Diddy" Combs rape lawsuit has sought her own representation with attorneys.
The gyroelongated square pyramid is a Johnson solid (specifically, J 10) constructed by augmenting one a square pyramid. Similarly, the gyroelongated square bipyramid ( J 17 ) is a deltahedron (a polyhedron whose faces are all equilateral triangles ) constructed by replacing both squares of a square antiprism with a square pyramid.
The star-studded gala, also attended by Olivia Munn, David Letterman, Alec and Hilaria Baldwin, Jon Hamm, Tom Hanks and Martin Short, marks Davidson’s first red carpet appearance since last year.
