In Euclidean geometry, the Mohr–Mascheroni theorem states that any geometric construction that can be performed by a compass and straightedge can be performed by a compass alone. This theorem refers to geometric constructions which only involve points and circles, since it is not possible to draw straight lines without a straightedge.
