How many sides does a heptagon have?

A heptagon is defined as a seven-sided polygon. The term "heptagon" stems from the Greek word "hepta," which means seven. In geometry, polygons are classified based on the number of sides they have, and knowing these classifications helps in visualizing and understanding various geometric shapes.

For instance, a triangle has three sides, a quadrilateral has four sides, a pentagon has five sides, a hexagon has six, and so on. Therefore, when identifying a heptagon, recognizing that it specifically refers to a seven-sided figure is key to arriving at the correct answer. This foundational knowledge about the characteristics of polygons aids in geometry and also supports problem-solving in mathematics more broadly.
