The 8Gon, also known as the octagon, is a polygon with eight sides. It is a fundamental shape in geometry, and understanding its properties and characteristics is crucial for various mathematical and real-world applications. In this comprehensive guide, we will delve into the fundamentals of 8Gon geometry, exploring its definition, properties, and uses.
Definition and Properties
An 8Gon is a closed shape with eight straight sides, where each side is called an edge, and each corner is called a vertex. The sum of the interior angles of an 8Gon is 1080 degrees, which can be calculated using the formula (n-2) * 180, where n is the number of sides. The 8Gon has several distinct properties, including symmetry, where it can be divided into two or more identical parts, and regularity, where all sides and angles are equal.
Types of 8Gons
There are several types of 8Gons, including regular, irregular, convex, and concave. A regular 8Gon is an 8Gon with all sides and angles equal, while an irregular 8Gon has sides and angles of different lengths and measures. A convex 8Gon is an 8Gon where all interior angles are less than 180 degrees, and a concave 8Gon has at least one interior angle greater than 180 degrees.
| Type of 8Gon | Properties |
|---|---|
| Regular 8Gon | All sides and angles equal |
| Irregular 8Gon | Sides and angles of different lengths and measures |
| Convex 8Gon | All interior angles less than 180 degrees |
