Sphere Geometry Diagram - Planes, Axes, and Cross-Sectional Triangle #2370872 (License: Personal Use)

This line-drawing diagram depicts a sphere intersected by two perpendicular planes: one horizontal (equatorial) and one vertical (meridional), forming orthogonal axes. A triangular cross-section originates from the sphere’s center and extends to the surface, illustrating vector components or solid angle concepts. Dashed lines indicate hidden edges for depth perception.

Used in educational contexts-calculus, vector analysis, or astronomy-to explain spherical coordinates, solid angles, or 3D geometric reasoning; targets students and instructors seeking visual aids for spatial concepts.
