Anhedral vs. Dihedral — What's the Difference?

(mineralogy) Lacking sharp, recognisable crystal faces.

Formed by or having two plane faces; two-sided.

(aeronautics) the downward slope of an aircraft’s wing

Relating to, having, or forming a dihedral angle.

A dihedral angle.

A dihedral group.

(Aeronautics) The upward or downward inclination of an aircraft wing from true horizontal.

(mathematics) An angle between two plane surfaces

(aeronautics) The upward slope of an aircraft's wing

(chemistry) The angle between pairs of chemical bonds separated by a third bond

(mathematics) Consisting of, relating to or contained between two plane surfaces.

(of a kite or an aeroplane) Having wings that form a dihedral angle, especially when the angle between the upper sides is less than 180°.

(aviation) Of wing pairs, inclined at an upward angle to each other.

Having two plane faces; as, the dihedral summit of a crystal.

Of a kite or an aëroplane, having wings that make with one another a dihedral angle, esp. when the angle between the upper sides is less than 180°.

Of wing pairs, inclined at an upward angle to each other.
