Sokszögek

Sokszögek are closed, two-dimensional geometric figures formed by straight line segments. These line segments are called sides, and they meet at points called vertices. The number of sides a polygon has determines its name and its properties. For example, a polygon with three sides is called a triangle, a polygon with four sides is a quadrilateral, and a polygon with five sides is a pentagon. As the number of sides increases, so does the complexity of the polygon, with figures like hexagons (six sides), heptagons (seven sides), and octagons (eight sides) becoming more common.

Polygons can be classified in several ways. They can be either convex or concave. A convex polygon is one where all interior angles are less than 180 degrees, and any line segment connecting two points within the polygon lies entirely within the polygon. A concave polygon, conversely, has at least one interior angle greater than 180 degrees, meaning a line segment connecting two points within it might pass outside the polygon. Another important classification is regular versus irregular polygons. In a regular polygon, all sides are of equal length, and all interior angles are equal. An irregular polygon does not possess these uniform characteristics. The sum of the interior angles of a polygon with n sides can be calculated using the formula (n-2) * 180 degrees. This fundamental property is crucial in understanding polygon geometry and solving related problems.
