{{Short description|Subdivision of a planar object into triangles}} {{refimprove|date=May 2024}} In [[geometry]], a '''triangulation''' is a subdivision of a [[plane (geometry)|planar object]] into triangles, and by extension the subdivision of a higher-dimension geometric object into [[simplex|simplices]]. Triangulations of a three-dimensional volume would involve subdividing it into [[tetrahedra]] packed together. In most instances, the triangles of a triangulation are required to meet edge-to-edge and vertex-to-vertex.
