### What is the Meaning of: Polygon | Concept and Definition of: Polygon

A polygon is a portion of plan bounded by straight lines. It is a geometric figure that is formed by non-alienated consecutive segments, which receive the name of sides.
There are several classes of polygons. Polygon means simple one where two of his non-consecutive edges don't intersect. On the other hand, concerning the complex polygon, two of its consecutive edges intersect.
Furthermore, it is appropriate to mention other polygons: the convex (crossing a line, it does not intersect more than two points), the concave (when it crosses a line, it may cross more than two points), the regular (sides and angles are equal), the irregular (sides and angles are unequal), the equilateral (all sides are equal) and the equiangle (all angles are equal).
With regard to the form of his side, polygons can be straight (its sides are straight segments) or curved (at least one of its sides is curved). On the other hand, if the polygon has more than two dimensions, it may be either polyhedron (in three dimensions), polycore (in four dimensions) or well polytope (for n-dimensional).
Polygons whose sides are not on the same plane are curved polygons.
In addition to geometry, a polygon is an urban unit developed in an area of land having been delineated for purposes of cadastral valuation, urban development, industrial planning or similar purposes.
Finally, a polygon with shooting is a space approved for shooting practice, meet the safety requirements.
