#angles
- Adjacent — Located in the immediate vicinity, directly neighboring, or attached to something; in geometry, it describes angles that share a common vertex and a common side, lying on opposite sides of that common side. In a general sense, it refers to administrative, structural, or territorial elements that share a common border or are directly connected in a network.
- Alternate — Succeeding in a regular manner, one element after another; arranged on either side of an axis or line at different points. In botany, it describes leaves set successively on the stem, at different heights, one by one. In geometry, it refers to angles formed by two lines cut by a transversal, located on opposite sides of it.
- Alternate — Masculine plural form of the adjective 'altern'; describes elements, structures, or bodies arranged successively, one after another, by turns, on an axis, or located on opposite sides of a dividing line (e.g., alternate interior angles).
- Anglesey — A large island situated off the north-west coast of Wales, in the Irish Sea, constituting a well-defined administrative island county within the United Kingdom. Separated from the Welsh mainland by the Menai Strait, this geographical and historical entity, known in Welsh as Ynys Môn, houses remarkable prehistoric archaeological sites, megalithic monuments, and was a major spiritual and religious center for Druids during Celtic antiquity.
- Angles — A West Germanic people originating from the Angeln region (located in present-day Schleswig-Holstein) who, starting in the 5th century AD, migrated in mass and settled in Great Britain alongside the Saxons and Jutes. This well-defined structural ethnic group founded early medieval kingdoms (such as Mercia, Northumbria, and East Anglia) and played a fundamental historical role in the ethnogenesis of the English people, giving their name to both the country (England) and the English language.
- Red and green kangaroo paw — An iconic species of the Anigozanthos genus, famous as the floral emblem of Western Australia, remarkable for the spectacular chromatic contrast of its inflorescences. The structural plant develops simple or poorly branched flowering stalks, covered with fiery red hairs at the upper part, from which intense emerald-green tubular flowers emerge, requiring strict drainage conditions and a warm climate to survive.
- Anisogonic — Having unequal angles; a polygon or geometric figure whose internal angles are not identical in measure, although the sides may sometimes retain symmetrical proportions. The term is used rarely in higher geometry or crystallography to describe asymmetric polygonal structures or crystal lattices that deviate from isogonic or regular shapes.
