A pentagon is defined as a polygon with five sides and five angles. The prefix "penta-" comes from Greek, meaning "five." Therefore, when determining the number of sides in a pentagon, it is essential to recognize that its structure consists of five line segments connecting five vertices. This fact solidly supports the identification of the pentagon as having five sides, making the choice of five sides the accurate and correct response to the question. Understanding the terminology used in geometry, especially for polygons, helps clarify the properties and classifications of different shapes.
