A multisided figure that represents area on a map A feature defined by the arcs that make up its boundary Every polygon contains one label point within its boundary Polygons have attributes that describe the geographic feature they represent
A closed plane figure formed by three or more line segments that do not cross over each other (cf What Are Tessellations Discussion)
A two-dimensional figure with three or more sides Polygons represent features too large to be depicted as points or lines Polygons have length (perimeter) as well as an area
one whose perimeter consists of more than four sides; any figure having many angles
A polygon is a closed convex geometric figure with three of more sides A regular polygon is one with equal sides and equal interior angles Some special polygons: triangle: a polygon of three sides quadrilateral: a polygon of four sides pentagon: a polygon of five sides hexagon: a polygon of six sides heptagon: a polygon of seven sides octagon: a polygon of eight sides nonagon: a polygon of nine sides decagon: a polygon of ten sides n-gon: a polygon of n sides
A plane figure bounded by a number of straight lines In a regular polygon, all the sides are equal and all the internal angles are equal
A closed curve formed only by line segments that meet at their endpoints (called vertices) See also: simple closed curve
A feature used to represent areas A polygon is defined by the lines that make up its boundary and a point inside its boundary for identification Polygons have attributes that describe the geographic feature they represent
An area bordered by three or more straight edges, with a vertex in every corner Parts of the polygon are
A closed figure formed by three or more line segments that do not intersect other than at the vertices
Line segments joined together to form a closed figure Rectangles, squares, pentagons are all examples of polygons
2 dimensional vector object (i e , has area) Polygons are defined by a set of arcs with a common topology
A polygon is a flat, or plane closed figure made up of at least 3 lines Triangles, rectangles, octagons, and all other flat figures that have 3 or more sides are polygons Here is a dodecagon: (a polygon with 12 sides!)
a closed geometric entity used to graphically represent area features with associated attributes
a flat shape with three or more sides. In geometry, any closed curve consisting of a set of line segments (sides) connected such that no two segments cross. The simplest polygons are triangles (three sides), quadrilaterals (four sides), and pentagons (five sides). If none of the sides, when extended, intersects the polygon, it is a convex polygon; otherwise it is concave. A polygon with all sides equal is equilateral. One with all interior angles equal is equiangular. Any polygon that is both equilateral and equiangular is a regular polygon (e.g., equilateral triangle, square)
closed broken line in a plane The line segments are called sides and their end points are the vertices
1 A feature used to represent areas A polygon is defined by the lines that make up its boundary and a point inside its boundary for identification Polygons have attributes that describe the geographic feature they represent 2 An ARC/INFO coverage feature class used to represent areas Polygon attributes, stored in a polygon attribute table (PAT), describe the geographic feature they represent
(n ) A planar shape created by a set of connected line segments (or vectors) that form vertexes at their meeting points Note that an n-gon is a polygon with an undetermined number of sides
Two-dimensional closed shape, bounded by line segments, typically with exactly two line segments, or sides, meeting at each vertex The faces of polyhedra are polygons
A coverage feature class used to represent areas A polygon is defined by the arcs that make up its boundary and a point inside its boundary for identification Polygons have attributes (PAT) that describe the geographic feature they represent
A polygonal figure the sides of which are vectors representing several forces acting simultaneously upon one point, so that the vector necessary to make the figure closed is the resultant of those forces
a geometric figure formed by connecting, with straight lines, every qth point out of p regularly spaced points that lie on the circumference of a circle
A graph of a frequency distribution with values of the variable on the x-axis and the number of observations on the y-axis; data points are plotted at the midpoints of the intervals and are connected with a straight line
