Polygon In mathematics, a polygon is a closed geometric shape that is made up of a finite number of straight line segments (edges) that are joined together end-to-end. The point where the two segments meet is called a vertex. The segments and the space inside the polygon define the polygon. Polygons can be broadly categorized into two types: regular and irregular. A regular polygon is one in which all of its sides are the same length and all of its angles are congruent (equal). An irregular polygon is one in which the sides are of different lengths and the angles are not congruent Polygon Naming Conventions Here is a list of the names of polygons, along with the number of sides they have: Triangle : 3 sides Quadrilateral : 4 sides Pentagon : 5 sides Hexagon: 6 sides Heptagon: 7 sides Octagon: 8 sides Nonagon: 9 sides Decagon: 10 sides Hendecagon or Undecagon: 11 sides Dodecagon: 12 sides Triskaidecagon or Tridecagon: 13 sides Tetradecagon:...
