A polygon with all sides of the same length is referred to as a regular polygon. In a regular polygon, not only are all the sides equal in length, but all the interior angles are also equal. This characteristic gives regular polygons a level of symmetry and uniformity that makes them visually appealing.
For example, a regular triangle (or equilateral triangle) has three equally long sides and three equal angles of 60 degrees. Similarly, a square is a regular polygon with four sides of equal length and four right angles. Other examples include regular pentagons, hexagons, and so forth.
The concept of regular polygons is important in various fields, including mathematics, architecture, and design. Their symmetrical properties allow for efficient tiling and structure formation, making them a popular choice in both natural formations and human-made designs.
In summary, a regular polygon is defined by having all sides and angles equal, showcasing both aesthetic appeal and functional advantages in numerous applications.
