In geometry, the crossbar theorem states that if a ray AD lies between rays AC and AB, meaning D lies in the interior of angle CAB, then ray AD must intersect the line segment BC.

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.
