High School Math : How to find the perimeter of a polygon

Regular polygons. In Euclidean geometry , a regular polygon is a polygon that is equiangular all angles are equal in measure and equilateral all sides have the same length. Regular polygons may be either convex or star. In the limit , a sequence of regular polygons with an increasing number of sides approximates a circle , if the perimeter or area is fixed, or a regular apeirogon effectively a straight line , if the edge length is fixed.

These properties apply to all regular polygons, whether convex or star. A regular n -sided polygon has rotational symmetry of order n. All vertices of a regular polygon lie on a common circle the circumscribed circle ; i. That is, a regular polygon is a cyclic polygon. Together with the property of equal-length sides, this implies that every regular polygon also has an inscribed circle or incircle that is tangent to every side at the midpoint.

Thus a regular polygon is a tangential polygon. A regular n -sided polygon can be constructed with compass and straightedge if and only if the odd prime factors of n are distinct Fermat primes. See constructible polygon. The symmetry group of an n -sided regular polygon is dihedral group D n of order 2 n : D 2 , D 3 , D 4 , It consists of the rotations in C n , together with reflection symmetry in n axes that pass through the center.

If n is even then half of these axes pass through two opposite vertices, and the other half through the midpoint of opposite sides. If n is odd then all axes pass through a vertex and the midpoint of the opposite side. All regular simple polygons a simple polygon is one that does not intersect itself anywhere are convex. Those having the same number of sides are also similar.

In certain contexts all the polygons considered will be regular. In such circumstances it is customary to drop the prefix regular. For instance, all the faces of uniform polyhedra must be regular and the faces will be described simply as triangle, square, pentagon, etc.

As n approaches infinity, the internal angle approaches degrees. For a regular polygon with 10, sides a myriagon the internal angle is However the polygon can never become a circle. For this reason, a circle is not a polygon with an infinite number of sides. The diagonals divide the polygon into 1, 4, 11, 24, For a regular n -gon inscribed in a unit-radius circle, the product of the distances from a given vertex to all other vertices including adjacent vertices and vertices connected by a diagonal equals n.

For a regular simple n -gon with circumradius R and distances d i from an arbitrary point in the plane to the vertices, we have [1].

For a regular n -gon, the sum of the perpendicular distances from any interior point to the n sides is n times the apothem [3] : p. The circumradius R from the center of a regular polygon to one of the vertices is related to the side length s or to the apothem a by. For constructible polygons , algebraic expressions for these relationships exist; see Bicentric polygon Regular polygons.

The sum of the perpendiculars from a regular n -gon's vertices to any line tangent to the circumcircle equals n times the circumradius. The sum of the squared distances from the vertices of a regular n -gon to any point on its circumcircle equals 2 nR 2 where R is the circumradius.

These tilings are contained as subsets of vertices, edges and faces in orthogonal projections m -cubes. The area A of a convex regular n -sided polygon having side s , circumradius R , apothem a , and perimeter p is given by [7] [8].

Of all n -gons with a given perimeter, the one with the largest area is regular. Some regular polygons are easy to construct with compass and straightedge ; other regular polygons are not constructible at all.

The ancient Greek mathematicians knew how to construct a regular polygon with 3, 4, or 5 sides, [20] : p. If not, which n -gons are constructible and which are not? Carl Friedrich Gauss proved the constructibility of the regular gon in Five years later, he developed the theory of Gaussian periods in his Disquisitiones Arithmeticae. This theory allowed him to formulate a sufficient condition for the constructibility of regular polygons:. A full proof of necessity was given by Pierre Wantzel in The result is known as the Gauss—Wantzel theorem.

Equivalently, a regular n -gon is constructible if and only if the cosine of its common angle is a constructible number —that is, can be written in terms of the four basic arithmetic operations and the extraction of square roots. A regular skew polygon in 3-space can be seen as nonplanar paths zig-zagging between two parallel planes, defined as the side-edges of a uniform antiprism. All edges and internal angles are equal. More generally regular skew polygons can be defined in n -space.

Examples include the Petrie polygons , polygonal paths of edges that divide a regular polytope into two halves, and seen as a regular polygon in orthogonal projection.

In the infinite limit regular skew polygons become skew apeirogons. A non-convex regular polygon is a regular star polygon. The most common example is the pentagram , which has the same vertices as a pentagon , but connects alternating vertices. If m is 2, for example, then every second point is joined.

If m is 3, then every third point is joined. The boundary of the polygon winds around the center m times. All regular polygons are self-dual to congruency, and for odd n they are self-dual to identity. In addition, the regular star figures compounds , being composed of regular polygons, are also self-dual.

A uniform polyhedron has regular polygons as faces, such that for every two vertices there is an isometry mapping one into the other just as there is for a regular polygon. A quasiregular polyhedron is a uniform polyhedron which has just two kinds of face alternating around each vertex.

A regular polyhedron is a uniform polyhedron which has just one kind of face. The remaining non-uniform convex polyhedra with regular faces are known as the Johnson solids. A polyhedron having regular triangles as faces is called a deltahedron.
