Wings are angled backwards, or swept, to enhance aerodynamic efficiency at high speeds. This design reduces drag, allowing aircraft to maintain better performance and stability. Additionally, swept wings help delay the onset of shock waves during supersonic flight, making them essential for modern jet aircraft. The backward angle also helps in balancing the airplane by improving lift distribution along the wing span.
