Adjacent or adjacency may refer to:

Adjacent (graph theory)
This is a glossary of graph theory. Graph theory is the study of graph (discrete mathematics), graphs, systems of nodes or vertex (graph theory), vertices connected in pairs by lines or #edge, edges.
Symbols
A
...
, two vertices that are the endpoints of an edge in a graph

Adjacent (music)
In music, a step, or conjunct motion,Bonds, Mark Evan (2006). ''A History of Music in Western Culture'', p.123. 2nd ed. . is the difference in pitch between two consecutive notes of a musical scale. In other words, it is the interval betwee ...
, a conjunct step to a note which is next in the scale

Adjacent angles
In Euclidean geometry, an angle is the figure formed by two rays, called the '' sides'' of the angle, sharing a common endpoint, called the ''vertex'' of the angle.
Angles formed by two rays lie in the plane that contains the rays. Angles ...
, two angles that share a common ray

Adjacent channel
In broadcasting an adjacent channel is an AM, FM, or TV channel that is next to another channel. First-adjacent is immediately next to another channel, second-adjacent is two channels away, and so forth. Information on adjacent channels is ...
in broadcasting, a channel that is next to another channel
*
Adjacency matrix
In graph theory and computer science, an adjacency matrix is a square matrix used to represent a finite graph. The elements of the matrix indicate whether pairs of vertices are adjacent or not in the graph.
In the special case of a finite simp ...
, a matrix that represents a graph

Adjacency pairs In linguistics, an adjacency pair is an example of conversational turn-taking. An adjacency pair is composed of two utterances by two speakers, one after the other. The speaking of the first utterance (the first-pair part, or the first turn) provo ...
in pragmatics, paired utterances such as a question and answer

Adjacent side (polygon)
In geometry, a polygon () is a plane figure that is described by a finite number of straight line segments connected to form a closed '' polygonal chain'' (or ''polygonal circuit''). The bounded plane region, the bounding circuit, or the two ...
, a side that shares an angle with another given side

Adjacent side (right triangle)
A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices ''A'', ''B'', and ''C'' is denoted \triangle ABC.
In Euclidean geometry, any three points, when non-collinear ...
, the side (or cathetus) of a right triangle that touches a given non-right angle
