octagon
8 sided polygon
An octagon is a polygon with 8 sides and 8 angles. The word octagon is derived from the Greek words octo, meaning eight, and gonia, meaning angle. In an octagon, each of the eight angles measures 135 degrees, and the sum of all interior angles is 1080 degrees.
To find the area of an octagon, you need to know the length of its apothem (the distance from the center of the octagon to the midpoint of any side). The formula for finding the area of an octagon is:
Area = (apothem x perimeter) / 2
where the perimeter of the octagon is simply 8 times the length of one of its sides.
There are several real-world examples of octagons, including stop signs and various types of building structures. In construction, octagonal shapes are often used to create a visually interesting design, while also providing structural strength and stability.
