What polygon has 6 sides and 6 angles?
- Statement of the given problem,
- How many sides has a regular polygon if the sum of its interior angles is 48 right angles?
- Let N denotes number of sides of the given regular polygon.
- Hence from above data we get following relation,
- N* (180° - 360°/N) = 48*90°
- N* (1 - 2/N)*180° = 48*90°
- or N - 2 = 48*90°/180° = 24
- or N = 24 + 2 = 26 [Ans]

The hexagon calculator allows you to calculate several interesting parameters of the 6-sided shape that we usually call a hexagon. Using this calculator is as simple as it can possibly get with only one of the parameters needed to calculate all others, as well as including a built-in length conversion tool for each of them.
What is the apothem of a triangle?
Just as a reminder, the apothem is the distance between the midpoint of any of the sides and the center. It can be viewed as the height of the equilateral triangle formed taking one side and two radii of the hexagon (each of the colored areas in the image above). Alternatively one can also think about the apothem as the distance between the center and any side of the hexagon, since the euclidean distance is defined using a perpendicular line.
What are the two values that are important in a hexagon?
Another pair of values that are important in a hexagon are the circumradius and the inradius . The circumradius is the radius of the circumference that contains all the vertices of the regular hexagon. The inradius is the radius of the biggest circle contained entirely within the hexagon.
How to get exotic shapes?
For example, if you divide the hexagon in half (from vertex to vertex) you get 2 trapezoids, and you can calculate the area of the hexagon as the sum of both, using our trapezoid area calculator. You could also combine two adjacent triangles to construct a total of 3 different rhombuses, and calculate the area of each separately. You can even decompose the hexagon in one big rectangle (using the short diagonals) and 2 isosceles triangles!
How to find the height of a triangle?
We will call this a. And the height of a triangle will be h = √3/2 * a which is the exactly value of the apothem in this case. We remind you that √ means square root. Using this we can start with the maths:
What are the symmetries of a hexagon?
These symmetries express nine distinct symmetries of a regular hexagon. John Conway labels these by a letter and group order. r12 is full symmetry, and a1 is no symmetry. p6, an isogonal hexagon constructed by three mirrors can alternate long and short edges, and d6, an isotoxal hexagon constructed with equal edge lengths, but vertices alternating two different internal angles. These two forms are duals of each other and have half the symmetry order of the regular hexagon. The i4 forms are regular hexagons flattened or stretched along one symmetry direction. It can be seen as an elongated rhombus, while d2 and p2 can be seen as horizontally and vertically elongated kites. g2 hexagons, with opposite sides parallel are also called hexagonal parallelogons .

How to travel around a polygon?
When you travel around the outside of a polygon (which I hope you'll concede is possible), starting at one vertex, you travel off along one side until you reach the next vertex, then continue on another side until you reach another vertex, and you keep going until you get back to the one you started with. Thus, your journey goes vertex-side, vertex-side, etc., pairing off the vertices and sides. Thus, there are the same number of sides as vertices.

Overview
In geometry, a hexagon (from Greek ἕξ, hex, meaning "six", and γωνία, gonía, meaning "corner, angle") is a six-sided polygon or 6-gon. The total of the internal angles of any simple (non-self-intersecting) hexagon is 720°.
Regular hexagon
A regular hexagon has Schläfli symbol {6} and can also be constructed as a truncated equilateral triangle, t{3}, which alternates two types of edges.
A regular hexagon is defined as a hexagon that is both equilateral and equiangular. It is bicentric, meaning that it is both cyclic (has a circumscribed circle) and tangential (has an inscribed circle).
Symmetry
The regular hexagon has D6 symmetry. There are 16 subgroups. There are 8 up to isomorphism: itself (D6), 2 dihedral: (D3, D2), 4 cyclic: (Z6, Z3, Z2, Z1) and the trivial (e)

Hexagonal structures
From bees' honeycombs to the Giant's Causeway, hexagonal patterns are prevalent in nature due to their efficiency. In a hexagonal grid each line is as short as it can possibly be if a large area is to be filled with the fewest hexagons. This means that honeycombs require less wax to construct and gain much strength under compression.

In addition to the regular hexagon, which determines a unique tessellation of the plane, any irregular hexagon which satisfies the Conway criterion will tile the plane.
