# Octagon – Definition & Properties

In geometry, the shape octagon is characterized as a polygon with 8 sides & 8 angles. There are 8 vertices as well as a total of 8 edges, for a maximum of 7 vertices as well as 8 edges. An octagon is defined as a two-dimensional flat structure having 8 sides. Each of the sides of an __octagon__ is linked with each endpoint to make a structure. Their sides remain parallel to each other; they are not twisted or linked in any way.

**What is a Hexagon?**

What is the first thing that leaps to mind when you hear the word hexagon? Let’s talk about what a __hexagon__ is. As the name implies, a hexagon may be broken into 2 parts: the very first “hex,” which indicates six, as well as the second-word “gon,” which can be described as any particular figure’s angle or edge. The name hexagon comes from Greek terminology. The shape is called a hexagon because it has a total of six sides.

A hexagon is also known as a 6 – sided shape. Any given hexagon’s interior angles add up to 120 °. In this post, we’ll learn more about hexagons and their characteristics.

**How Many Sides Does a Hexagon Have?**

A hexagon is defined as a geometric polygon having 6 sides as well as angles in 2 dimensions. It has no rounded or curved sides, with all of its lines that are straight. The internal angles of a regular hexagon sum up to a total of 720 degrees.

When wondering “how many sides does a hexagon have?” it’s useful to know whatever sort of hexagon we’re talking about. Every hexagon has 6 sides, each having its unique set of properties.

Hexagons are available in four distinct forms. Hexagons are classified into four categories: regular hexagons, irregular hexagons, concave hexagons, & convex hexagons.

**How to Determine the Perimeter of any given Hexagon?**

Let’s look at how to get the perimeter of any hexagon. The perimeter is calculated by multiplying six times the length of a hexagon’s side.

**Example 1:** Any hexagon, for example, has a side length of 5 cm. Determine the hexagon’s perimeter.

The formula to calculate the perimeter of the hexagon is equal to 6*side

We’ve previously learned how to calculate the perimeter of a hexagon, 6*5, which is equal to 30 cm.

**Octagon’s Perimeter**

Now calculate the perimeter of an octagon. Because all sides of an octagon have equal length.

The circumference of an octagon is calculated as 8 * specific side.

**Example 1:** Suppose there is an octagon with all of its sides measuring 6 cm. How do you find the octagon’s perimeter?

**Solution:**

The octagon’s circumference = 8* side

As a result, the circumference of the supplied octagon is 8*6 = 48 cm.

**Example 2:** For example, an octagon has a side length of 5 cm. Determine the octagon’s perimeter.

**Solution:**

Side of the given octagon = 5 cm

The formula to calculate the perimeter of the octagon is equal to 8*side

We’ve previously learned how to calculate the perimeter of an octagon, 8*5, which is equal to 40 cm.

**Octagons, Regular and Irregular Octagons**

Any regular octagon is defined as a closed object with equal-length sides as well as interior angles which are of equal length. It has 8 symmetric lines along with a rotating equilibrium of order 8. The internal angle of a given regular octagon at every vertex is 135 degrees. The median angle measures 45 °.
