What is the number of sides in a pentagon?

A pentagon is a specific type of polygon characterized by having five sides and five angles. The prefix "penta-" in Greek means five, which directly indicates the number of sides in this geometric shape. When teaching young students about polygons, it is essential to emphasize the connection between the name of the shape and its attributes, such as the number of sides. Thus, recognizing that a pentagon has five sides is crucial for understanding basic geometry. This knowledge can further be applied when identifying other polygons by their respective prefixes, such as "triangle" for three sides or "quadrilateral" for four sides.
