## Regular Polygon

### A regular polygon is a polygon that has all sides of equal length and all interior angles of equal measure

A regular polygon is a polygon that has all sides of equal length and all interior angles of equal measure. In other words, it is a polygon that is both equilateral (having all sides equal) and equiangular (having all angles equal). The most common examples of regular polygons are equilateral triangles, squares, pentagons, hexagons, and so on.

Regular polygons have several distinguishing properties. Here are a few:

1. Side Lengths: In a regular polygon, all sides are congruent (i.e., equal in length). This means that if one side length is given, then all side lengths can be determined.

2. Exterior Angles: The measure of each exterior angle of a regular polygon is equal to 360 degrees divided by the number of sides. For example, in a regular hexagon (a polygon with six sides), each exterior angle measures 60 degrees (360°/6 = 60°).

3. Interior Angles: The measure of each interior angle of a regular polygon can be determined using the formula (n-2) * 180° / n, where n represents the number of sides. For example, in a regular pentagon (a polygon with five sides), each interior angle measures (5-2) * 180° / 5 = 108°.

4. Symmetry: Regular polygons possess rotational symmetry. This means that they can be rotated by a certain angle (usually the measure of one interior angle) and still look the same.

Regular polygons are commonly used in various areas of mathematics and geometry. They have special properties that make them easier to work with and analyze compared to irregular polygons. Additionally, regular polygons often appear in nature, art, and architecture due to their visually pleasing and symmetrical nature.
