A geodesic dome is a spherical structure made up of a network of triangles. This design allows the dome to distribute weight evenly, making it strong and stable. The triangles create a lightweight yet sturdy framework, which can be built using various materials like wood, metal, or plastic. These domes are often used in architecture and environmental design because they can withstand harsh weather conditions. Famous architect Buckminster Fuller popularized the geodesic dome in the 20th century, showcasing its efficiency and versatility in various applications, from homes to exhibition spaces.
