What defines a polygon in geometry?

  1. A closed three-dimensional figure

  2. A simple, closed two-dimensional figure composed of line segments

  3. A complex three-dimensional shape with line segments

  4. A figure with curved edges

The correct answer is: A simple, closed two-dimensional figure composed of line segments

A polygon is defined as a simple, closed two-dimensional figure composed of line segments. This definition encompasses key characteristics of polygons, such as being made up solely of straight line segments, ensuring that there are no curves in its structure. Also, the term "simple" denotes that the polygon does not intersect itself, and "closed" signifies that the figure is complete, with endpoints of the line segments meeting to form a continuous shape. Polygons can vary in the number of their sides (such as triangles, quadrilaterals, pentagons, etc.), but they will always conform to the criteria of being two-dimensional and composed of straight edges, distinguishing them from three-dimensional figures or other shapes that may include curved elements.
