Množina: angles

ETYM French angle, Latin angulus angle, corner; akin to uncus hook, Greek agkylos bent, crooked, angular, agkos a bend or hollow, AS. angel hook, fish-hook, German angel, and French anchor.
In mathematics, the amount of turn or rotation; it may be defined by a pair of rays (half-lines) that share a common endpoint but do not lie on the same line. Angles are measured in degrees (º) or radians (rads)—a complete turn or circle being 360º or 2p rads.
Angles are classified generally by their degree measures: acute angles are less than 90º; right angles are exactly 90º (a quarter turn); obtuse angles are greater than 90º but less than 180º; reflex angles are greater than 180º but less than 360º.
The space between two lines or planes that intersect; the inclination of one line to another; measured in degrees or radians.

1. To fish with a hook.
2. To move or proceed at an angle.

Množina: angle brackets

One of the pair of marks used to enclose matter.
1. An L-shaped metal bracket; SYN. angle iron.
2. Either of two punctuation marks (formed of angular parentheses) used to enclose textual material; SYN. bracket.

Množina: angle of attacks

The acute angle between the direction of the undisturbed relative wind and the chord of an airfoil.

Množina: angle of incidences

The angle that a line makes with a line perpendicular to the surface at the point of incidence; SYN. incidence angle.
Angle between direction of motion of waves and a line perpendicular to surface the waves are striking
Angle between a ray of light striking a mirror (incident ray) and the normal to that mirror. It is equal to the angle of reflection.

Množina: angle of reflections

The angle between a reflected ray and a line perpendicular to the reflecting surface at the point of incidence.
Angle between direction of motion of waves and a line perpendicular to surface the waves are reflected from.
Angle between a ray of light reflected from a mirror and the normal to that mirror. It is equal to the angle of incidence.

Množina: angle of refractions

The angle between a refracted ray and a line perpendicular to the surface between the two media at the point of refraction.
Angle between direction of motion of waves and a line perpendicular to surface the waves have been refracted from.
Angle between a refracted ray of light and the normal to the surface at which refraction occurred. When a ray passes from air into a denser medium such as glass, it is bent toward the normal so that the angle of refraction is less than the angle of incidence.

Množina: anglers

1. A fisherman who uses a hook and line; SYN. troller.
2. A scheming person; someone who schemes to gain an advantage.
Any of an order of fishes Lophiiformes, with flattened body and broad head and jaws. Many species have small, plantlike tufts on their skin. These act as camouflage for the fish as it waits, either floating among seaweed or lying on the sea bottom, twitching the enlarged tip of the threadlike first ray of its dorsal fin to entice prey.
There are over 200 species of angler fish, living in both deep and shallow water in temperate and tropical seas. The males of some species have become so small that they live as parasites on the females.
