| 41. | The notation for the dihedral group of order differs in geometry and abstract algebra.
|
| 42. | The answer is just the dihedral symmetry group Dih " n ".
|
| 43. | When two such planes intersect, the angle between them is a dihedral angle.
|
| 44. | However, many other aircraft parameters also have a strong influence on dihedral effect.
|
| 45. | Dihedral and an operable elevator were also included.
|
| 46. | A dihedral tailplane was also fitted to keep it clear of the propeller slipstream.
|
| 47. | Their symmetry group, the dihedral group of order 4, has eight elements.
|
| 48. | Below is an example with dihedral hexagonal symmetry.
|
| 49. | Fitted with unusually long suspension lines, the Bede Wing had almost no dihedral.
|
| 50. | A transversal plane may also form dihedral angles.
