WebProof. It can be easily proved by induction on ‘. Note that each way to add exactly ‘ 3 edges to make a cycle of length ‘ become a chordal graph is exactly a way to triangulate a convex ‘-side polygon by adding diagonals. The number of ways to triangulate a convex ‘-side polygon by adding diagonals is equal to the Catalan number. The In computational geometry, polygon triangulation is the partition of a polygonal area (simple polygon) P into a set of triangles, i.e., finding a set of triangles with pairwise non-intersecting interiors whose union is P. Triangulations may be viewed as special cases of planar straight-line graphs. When there are no holes or added points, triangulations form maximal outerpla…
