Regular Polygons

Regular polygons
Regular polygon is a polygon where all sides are of equal length, called equilateral sides, and where all angles are also equal, called equilateral angles.

Some regular polygons are so common that they have a special descriptive mathematical name:

 Number of sides Common name 3 Triangle 4 Square (Quadrilateral) 5 Pentagon 6 Hexagon 7 Heptagon 8 Octagon 9 Nonagon 10 Decagon 12 Dodecagon n n-gon
