Report on the Use of Various Solid Geometrical Shapes in Ancient Indian Constructions (Indigenous Knowledge Systems - IKS) Abstract: This report explores the profound and sophisticated use of solid geometrical shapes in ancient Indian architecture and construction, underscoring the advanced understanding of geometry and its practical applications in the Indian subcontinent. Ancient Indian constructions, which range from temples and forts to water reservoirs and cities, exhibit an intricate application of geometrical principles and shapes, demonstrating a blend of aesthetic beauty, functionality, and adherence to religious and cosmological concepts. Introduction: The ancient Indian architectural treatise, Vastu Shastra, along with other historical texts such as the Sulba Sutras, provides extensive guidelines on architectural design and construction techniques. These texts reveal that ancient Indian architects (sthapatis) and engineers possessed profound knowledge of geometry, mathemati
