diédrico
- Let's examine a plane with dihedral wings, meaning they point upwards in straight and level flight.
- dihedral angle
Examples
-
We assume that the link atoms are connected to the high-level layer with the same angular and dihedral values as the link atom hosts (LAHs, the atoms replaced by the link atoms in the model system) in the real system.

Highlighted carbon atoms are those involved in dihedral angles C-C-O-C and C-C-O-B as mentioned in the text; see PDF for image.

During recrystallization driven by the minimization of interfacial energies, the 'canary in the coal mine' is the dihedral angle, as this is the first part of the microstructure that will change.
Academic text (2018) -
Grain junctions are formed at the intersection of planar interfaces, with no evidence of modification towards the equilibrium melt-solid-solid dihedral angle (examples are arrowed).
Academic text (2018) -
In the subsolidus regime, textural equilibration, therefore, generally involves an increase in dihedral angles at three-grain junctions, and this also occurs by progressive rotation of large areas of interface.

In aircraft design, a dihedral wing configuration improves stability during flight.
-
The architect decided to incorporate dihedral angles to create a striking visual effect in the building's roof.
-
In geometry class, we learned that a dihedral angle is formed where two planes intersect.

Morphology
dihedral = hedron (semi-transparent) = di + hedral
Built from 'di-' (two) + the combining element '-hedral' (relating to faces/planes); the components indicate the geometric sense but are technical combining forms not familiar to average learners.
Etymology
Dihedral comes from the Greek parts di- 'two' and -hedral 'face'. So dihedral describes something that has an angle of 'two faces', like where two planes meet or the V-shape of airplane wings.
