Moreover, 15 pentagons have exactly three intervertex distances, and five heptagons have exactly four intervertex distances. The latter five are the regular octagon minus a vertex and the four dissimilar versions of a regular nonagon with two vertices removed.PeterFishburn...
regular polygon- a polygon with all sides and all angles equal isogon- an equiangular polygon foursquare,square- (geometry) a plane rectangle with four equal sides and four right angles; a four-sided regular polygon; "you can compute the area of a square if you know the length of its sid...
Sides Interior and exterior Interior angles Exterior angles Vertices Diagonals We will illustrate with a basic regular polygon, the hexagon. This is a familiar shape (think of the cells of a honeybee hive): Parts of a Regular Polygon Our hexagon has six congruent sides. It has six equal inter...
Convex Polygons –A convex polygon is a polygon with all interior anglesless than180°. In convex polygons, all diagonals are in the interior of the polygon. (Diagonalis aline segmentjoining any two non-consecutive vertices of a polygon) ...
Layer 1001 is a hug polygon with about 6M vertices any a million holes: I assume the main performance killer is the hole formation. Point taken. If my picture is correct, then it should be possible to optimize by turning the interaction check around: verbose l1in = input(1, 0) l2in ...
It is shown that any simple polygon with n vertices can be illuminated by at most ⌊(3n - 5)/4⌋ vertex π-floodlights. This improves the earlier bound n— 2, whereas the best lower bound remains 3n/5+c.
For a polygon P with n vertices, the vertex guarding problem asks for the minimum subset G of Pʼs vertices such that every point in P is seen by at least one point in G. This problem is NP-complete and APX-hard. The first approximation algorithm (Ghosh, 1987) involves decomposing ...

The second line contains the labels of edges 1, ..., N, interleaved with the vertices' labels (first that of the vertex between edges 1 and 2, then that of the vertex between edges 2 and 3, and so on, until that of the vertex between edges N and 1), all separated by one space...
6 This is a molecule consisting entirely of carbon atoms arranged as the vertices of a polyhedron, shown in Figure I.5 of the Introduction to this book. The map of this polyhedron is exactly that of the traditional soccer ball, with 12 pentagonal faces and 20 hexagonal faces. This was a...
