An octagon is a polygon with eight sides and eight angles
An octagon is a polygon with eight sides and eight angles. The word “octa” in octagon comes from the Greek word for eight. Each angle of an octagon measures 135 degrees, and the sum of all the interior angles of an octagon is 1080 degrees.
An octagon is a special type of polygon that is known for its symmetrical and regular shape. In a regular octagon, all sides and angles are equal. The regular octagon is often seen in architecture, such as the stop sign on the road, or in the design of some buildings.
To find the perimeter of an octagon, you can add up the lengths of all its sides. If the length of one side is given, you can simply multiply it by eight to get the total perimeter.
To find the area of a regular octagon, you can use the following formula:
Area = 2 * (1 + √2) * s^2
where “s” is the length of one side of the octagon.
