Dynamic Lateral Surface Development of a Cone

This GeoGebra example dynamically demonstrates the geometric process of unfolding a cone's lateral surface into a sector. Using constructions such as rotation, orthogonal planes, and cross-sections, it illustrates how a 3D cone is cut along its slant height and flattened into a 2D sector. Key concepts include the equivalence between the cone's base circumference and the sector's arc length, the co
