Commandino's Theorem

Geometry

Commandino's theorem, named after the Italian mathematician Federico Commandino (1509-1575), states that the four medians of a tetrahedron are concurrent at a single point, which divides each median in a ratio of three to one.

Has Statement Form

Entity-backed identity for the statement-form enum value this theorem already carries, resolved to a mathematics concept by an explicit value-to-entity map (phase 3 bucket conversion, docs\design_entity_backed_browse_buckets_20260928.md). The statement-form fact itself stays on the theorem unchanged.
