An octagon is a polygon with eight sides and eight angles
An octagon is a polygon with eight sides and eight angles. It is a two-dimensional figure that is formed by connecting eight straight line segments, called sides. The sides of an octagon are all equal in length and the interior angles are all equal, measuring 135 degrees each.
To visualize an octagon, you can imagine a stop sign or a regular eight-sided figure. Each of the angles in the octagon measures 135 degrees, which means that if you add up all the interior angles, the sum will be equal to 1080 degrees.
Octagons can be regular or irregular. A regular octagon has all sides and angles equal, while an irregular octagon has sides and angles that are different from each other. In everyday life, we can find examples of octagons in various objects such as stop signs, some traffic signs, or architectural designs.
Finding the area of an octagon can be done using different methods, such as splitting it into smaller shapes or by using formulas specific to octagons. The formula for finding the area of a regular octagon is A = 2a^2(1 + √2), where A represents the area and ‘a’ represents the length of each side.
In summary, an octagon is a polygon with eight sides and eight angles. It is a geometric shape that can be regular or irregular, and it has various real-life applications.
