Sphere and Plane Intersection GeoGebra Sketch

①This example demonstrates how to construct the intersection of a sphere and a plane in GeoGebra's 3D view, revealing the resulting circle and related points/segments. ②Core math concepts include solid geometry: the intersection of a plane with a sphere, spatial points, segments, vectors, and coordinate relationships. ③Construction highlights: from the summary, commands such as Intersect, Sphere, PointIn, Segment, Point, and Plane are used, with objects A, a, B, f, C, D, E, b defined—likely representing sphere center, radius, plane, and intersection points. ④Suitable for high school or early college students learning solid geometry or spatial analytic geometry, and as a teaching example for 3D construction in GeoGebra, illustrating fundamental spatial figure building and interactive manipulation.
