A polygon is closed shape with equal number of angles and sides. The sides are called edges and the two sides intersect to form vertices. A polygon with n sides would have n vertices and n angles.
The Greek word “octa” means 8 and “gon” means angles thus a polygon with eight angles is called an Octagon. The octagon also has 8 sides and can be classified regular; irregular based on the sides lengths. It can also be classified as concave or convex type based on the internal angles.
Some commonly seen octagon in real life
- An open umbrella is like an octagon.
- The stop sign we see is also in shape of an octagon.
