A dihedral angle is the angle between two intersecting planes or half-planes. In chemistry, it is the clockwise angle between half-planes through two...

In aeronautics, dihedral is the angle between the left and right wings (or tail surfaces) of an aircraft. "Dihedral" is also used to describe the effect...

Look up dihedral or polyhedral in Wiktionary, the free dictionary. Dihedral or polyhedral may refer to: Dihedral angle, the angle between two mathematical...

plane angles as they lie in the plane that contains the rays. Angles are also formed by the intersection of two planes; these are called dihedral angles. Two...

The dihedral angles for the edge-transitive polyhedra are: Coxeter, Regular Polytopes (1963), Macmillan Company Regular Polytopes, (3rd edition, 1973)...

the three dihedral angles for the sequences (2,3,4), (3,4,5), and (4,5,6). The next bond, from atom 6, is also oriented by a dihedral angle, so we have...

Define the vertex angle θa to be the angle BOC and define θb, θc correspondingly. Let ϕ a b {\displaystyle \phi _{ab}} be the dihedral angle between the planes...

dihedral angle of a rhombicuboctahedron can be determined by adding the dihedral angle of a square cupola and an octagonal prism: the dihedral angle of...

linear model is a hyperplane. The dihedral angle between two non-parallel hyperplanes of a Euclidean space is the angle between the corresponding normal...

In astronomy and celestial navigation, the hour angle is the dihedral angle between the meridian plane (containing Earth's axis and the zenith) and the...

{\displaystyle \Pi _{2}:a_{2}x+b_{2}y+c_{2}z+d_{2}=0} , the dihedral angle between them is defined to be the angle α {\displaystyle \alpha } between their normal directions:...

is a way to visualize energetically allowed regions for backbone dihedral angles ψ against φ of amino acid residues in protein structure. The figure...

themselves regular (n − 1)-dimensional simplices, and they have the same dihedral angle of cos−1(1/n). This can be seen by noting that the center of the standard...

which meet at antipodal points. It is an example of a digon, {2}θ, with dihedral angle θ. The word "lune" derives from luna, the Latin word for Moon. Great...

effects coming from design characteristics, such as high wings, dihedral angles or sweep angles. The second lateral motion is an oscillatory combined roll...

. The dihedral angle of a pentagonal antiprism between pentagon-to-triangle is 100.8 ∘ {\displaystyle 100.8^{\circ }} , and the dihedral angle of a pentagonal...

or antiperiplanar, describes the A−B−C−D bond angle in a molecule. In this conformer, the dihedral angle of the A−B bond and the C−D bond is greater than...

number of angles associated with each Platonic solid. The dihedral angle is the interior angle between any two face planes. The dihedral angle, θ, of the...

spherical angle is a particular dihedral angle; it is the angle between two intersecting arcs of great circles on a sphere. It is measured by the angle between...

In mathematics, a dihedral group is the group of symmetries of a regular polygon, which includes rotations and reflections. Dihedral groups are among the...
