Star polygons are a type of geometric figure that resemble stars. They are created by connecting points of a regular polygon in a specific sequence, skipping a certain number of vertices each time. The most common star polygons are formed from regular shapes like triangles, squares, and pentagons, resulting in visually striking designs. These shapes are often denoted using a notation that includes the number of points and the step size, such as 5/2 for a five-pointed star. Star polygons have applications in art, design, and mathematics, showcasing the beauty of symmetry and geometric relationships.
