The intercept theorem, also known as Thales's theorem in some traditions, the basic proportionality theorem, or the side splitter theorem, is a result in elementary geometry concerning the ratios of line segments created when two rays sharing a common starting point are cut by a pair of parallel lines.

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.
