How many sides does an octagon have?

An octagon is defined as a polygon that has eight sides. The term "octagon" derives from the Greek "okto," meaning eight, and "gon," which refers to angles or corners. Thus, when identifying the characteristics of an octagon, it is essential to recognize that it consistently has eight linear edges and eight vertices. This makes the option with eight sides the correct choice in this context. Understanding the terminology and definition of polygon types can help accurately identify their properties, ensuring clarity in distinguishing between shapes with different numbers of sides.
