This example demonstrates the generation of conic sections by rotating a plane to intersect a cone. It covers core concepts like ellipse, hyperbola, and parabola. Construction uses GeoGebra commands such as Cone, Plane, Rotate, and Intersect to build the 3D model and dynamic intersection curves. Suitable for high school or college math education to visualize conic section origins.
