In Euclidean geometry, a regular polygon is a (simple, non self-intersecting) polygon in a Euclidean space such that every segment? of the boundary of the polygon has the same length and every angle between two segments of the boundary of the polygon has the same angle measure. (The boundary of a regular polygon is sometimes called called a regular polygonal line)
We are using the circle constant .
Every regular polygon is the union of congruent triangles each with segments of length and respectively and an angle of between the two segments of length . As a result, the triangles are isosceles and the altitude from the center of the regular polygon to the third segment of the triangles bisects the angle: such that the angles between the circumradius and the altitude is . The length of the third segment is thus given by
The perimeter of a regular polygon (strictly speaking, a regular polygonal line) with sides and circumradius is given by the sequence of functions
The area of a regular polygon with sides and circumradius is given by the sequence of functions
