## Octagon

### An octagon is a polygon with eight sides and eight angles

An octagon is a polygon with eight sides and eight angles. Each side of an octagon is connected to its neighboring sides to form a closed shape. The sum of the interior angles of an octagon is equal to 1080 degrees. Each angle of a regular octagon (where all sides and angles are equal) measures 135 degrees.

To find the perimeter of an octagon, you add up the lengths of all eight sides. If the length of each side is given, you can simply multiply it by 8 to get the perimeter.

The area of an octagon can be calculated using various methods, depending on whether it is a regular or irregular octagon. For a regular octagon, which has equal side lengths, the area can be found by multiplying the square of the side length by 2 multiplied by the square root of 2.

If you have an irregular octagon, where the side lengths are not equal, you can calculate the area by dividing it into smaller shapes, such as triangles or rectangles, and finding the sum of their respective areas.

It is worth noting that an octagon is commonly found in architecture and design, particularly in the construction of buildings, such as gazebos and stop signs.
