Nietaangrenzende

Nietaangrenzende is a Dutch term meaning not adjacent. It is used to describe elements that do not share a boundary, edge, or immediate proximity. In mathematics and related fields, it often refers to pairs of elements that are not directly connected or neighboring, such as non-adjacent vertices in a polygon or non-adjacent vertices in a graph.

Spelling and punctuation vary. The base form is typically written as two words, niet aangrenzende, meaning not adjacent; some authors hyphenate as niet-aangrenzende, while others may use a less common single-word variant. The English equivalent is non-adjacent, and translations are context dependent.

In usage, the term helps distinguish between neighboring and non-neighboring elements. For example, in a polygon with vertices labeled consecutively, opposite vertices can be described as nietaangrenzende, whereas consecutive vertices are adjacent. In graph theory, two vertices are nietaangrenzende if there is no edge directly connecting them. The concept also appears in geography or map analysis when describing regions that do not share a border.

Overall, nietaangrenzende provides a precise way to describe non-proximity relations across disciplines, complementing terms for adjacency, proximity, or consecutive positioning. See also: adjacency, non-adjacency, nonconsecutive, opposite vertices.
