Mohr-Mascheroni Theorem

Geometry

In Euclidean geometry, the Mohr-Mascheroni theorem states that any geometric construction that can be performed with a compass and straightedge can also be performed using a compass alone, with no straightedge.

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.
