What has 8 sides and makes a cool shape? Learn all about octagons in this handy guide.

In geometry, an octagon (from Ancient Greek ὀκτάγωνον (oktágōnon) 'eight angles') is an eight-sided polygon or 8-gon. A regular octagon has Schläfli symbol {8} [1] and can also be constructed as a quasiregular truncated square, t {4}, which alternates two types of edges. A truncated octagon, t {8} is a hexadecagon, {16}.

An octagon is a closed two-dimensional figure with eight sides, eight vertices and eight interior angles. If all the sides and interior angles of an octagon are of equal measure, then it is called a regular octagon otherwise an irregular octagon. The other types of octagons such as convex and concave octagons are also explained in the next ...

Octagon is an eight-sided two-dimensional geometrical figure. An octagon consists of 8 interior angles and 8 exterior angles. The sum of the interior angles of an octagon is 1080°, and the sum of its exterior angles is 360°. There are 20 diagonals in an octagon. Octagons are classified into various types based upon their sides and angles.

First, have a play with an octagon: When all angles are equal and all sides are equal it is regular, otherwise it is irregular. A convex octagon has no angles pointing inwards. More precisely, no internal angles can be more than 180°. When any internal angle is greater than 180° it is concave. (Think: concave has a "cave" in it) Is it an Octagon?

Below are some properties of all octagons as well as properties specific to regular octagons. Properties of all octagons. 8 angles, 8 sides, and 8 vertices. The sum of interior angles is 1080°. The sum of all exterior angles is 360°. 20 diagonals. Properties of regular octagons. All 8 sides are equal. All 8 angles are equal.

2023年8月3日 · When all the eight sides and eight angles of an octagon are equal, it is a regular octagon. Otherwise, it is an irregular octagon. The below-given properties and formulas to find the perimeter, area and length of diagonals only apply to the regular octagon.

2023年5月29日 · There are various types of octagons, but the most common one is the regular Octagon, where all the sides and angles are equal. In a regular octagon, each interior angle measures 135 degrees, and the sum of all interior angles is 1080 degrees.

2024年1月6日 · Octagons possess 8 remarkable sides that come together to create a unique geometric shape. The key to understanding the beauty of octagons lies in their sides and the relationships between them. In a regular octagon, the magic unfolds as all eight sides are equal in length, and all eight angles are equal in measure.
