How many sides has a octagon

In geometry, Octagon is a polygon that has 8 sides and 8 angles. That means the number of vertices and edges of an octagon is 8, respectively. In simple words, the octagon is an 8-sided polygonalso called 8-gon, in a two-dimensional plane.

A 3D analog of the octagon can be the rhombicuboctahedron with the triangular faces on it like the replaced edges, if one considers the octagon to be a truncated square. If squares are constructed all internally or all externally on the sides of an octagon, then the midpoints of the segments connecting the centers of opposite squares form a quadrilateral that is both equidiagonal and orthodiagonal that is, whose diagonals are equal in length and at right angles to each other. The midpoint octagon of a reference octagon has its eight vertices at the midpoints of the sides of the reference octagon. If squares are constructed all internally or all externally on the sides of the midpoint octagon, then the midpoints of the segments connecting the centers of opposite squares themselves form the vertices of a square. A regular octagon is a closed figure with sides of the same length and internal angles of the same size. It has eight lines of reflective symmetry and rotational symmetry of order 8.

Now, what is a polygon? Very simple. It is a closed plane figure with at least three straight sides and angles, typically five or more. You are already familiar with some of my family members, like the triangle and the square. A stop sign is generally in the an octagon shape —a closed two-dimensional figure with eight sides and eight vertices. Depending on the measure of the sides and angles, octagons can be classified into the following types:. A regular octagon shape has eight equal sides and eight equal angles. All the sides are of equal length , and all the angles are of equal measure. In an irregular octagon shape , the eight sides and eight angles are unequal. All the sides are not equal in length, and all the angles are not equal in measure. An octagon that has all its angles pointing outside or no angles pointing inwards is a convex octagon shape. Convex octagons bulge outwards. The octagon in which at least one of the angles points inwards is a concave octagon shape.

Also, based on the length of these sides, octagons are classified as regular and irregular octagons. Maths Math Article Octagon. Convex and Concave Octagons Convex Octagon An octagon that has all its angles pointing outside or no angles pointing inwards is a convex octagon shape.

Hello and welcome to the octagon calculator , the ultimate tool for everything octangular. Here, we hope you will find an excellent tool for calculating the diagonals, perimeter, circumradius, inradius, and area of a regular octagon. In this octagon area calculator, you will also find the answers to the following questions: what is an octagon, how many sides does an octagon have, how to find the area of a regular octagon or how to draw an octagon. We will review the octagon definition, discuss the octagon angles and how they affect the octagon shape. On top of all that, we will see a few examples of real-world octagons including octagon tiles, flooring, and the famous "Octagon house".

Some of the examples include the following:. Perimeter Of A Parallelogram. This decomposition can be seen as 6 of 24 faces in a Petrie polygon projection plane of the tesseract. The point which defines it as different from other geometrical shapes is that it has 8 sides and 8 angles. Look up octagon in Wiktionary, the free dictionary. A regular octagon will have all its sides equal in length. If squares are built internally or externally on all the sides of an octagon, then the midpoints of the sections joining the centers of opposite squares form a quadrilateral: equi-diagonal and ortho-diagonal whose diagonals length are equal and they bisect each other at 90 degrees. Architects such as John Andrews have used octagonal floor layouts in buildings for functionally separating office areas from building services, such as in the Intelsat Headquarters of Washington or Callam Offices in Canberra. There are 20 diagonals in a regular octagon. However, these lines of symmetry can be drawn for regular octagons and this can be shown as:. Twelve bars of size 4, three bars of size 5 and two bars of size 6 are required.

Octagon is an eight-sided two-dimensional geometrical figure. An octagon consists of 8 interior angles and 8 exterior angles. There are 20 diagonals in an octagon.

In the previous section, you learned about the shape of an octagon with the help of an image. Solution : The length of the side of the given regular octagon is 10 cm. As we already know, the octagon is an 8-sided polygon. Truncated 6-cube. A skew octagon is a skew polygon with eight vertices and edges but not existing on the same plane. If we join the opposite vertices of a regular octagon, then the diagonals formed have the length equal to:. Area Of Polygon. The regular skew octagon is the Petrie polygon for these higher-dimensional regular and uniform polytopes , shown in these skew orthogonal projections of in A 7 , B 4 , and D 5 Coxeter planes. It is the sum of the length of all sides. On the regular octagon, there are eleven distinct symmetries. It is a closed plane figure with at least three straight sides and angles, typically five or more. Correct Incorrect. The interior of such an octagon is not generally defined. Example 1.
