How many sides does an octagon have?

An octagon is defined as a polygon with eight sides and eight angles. The term "octagon" is derived from the Greek words "okto," meaning eight, and "gonia," meaning angle. This geometric shape is commonly recognized in various contexts, such as stop signs, which are typically octagonal in shape.

When considering the characteristics of an octagon, it is important to note that all sides are generally of equal length in a regular octagon, and the internal angles measure 135 degrees each. The clarity of the octagon's definition is what makes the choice stating it has eight sides the correct one in this context.
