Triangulation (disambiguation)

Triangulation is the process of determining the location of a point by forming triangles to it from known points.

Triangulation may also refer to:

Graph theory

 * Plane triangulation, and a maximal planar supergraph of a graph G may be called a triangulation of G
 * Triangulated graph, and a chordal completion of a graph G may be called a triangulation of G
