With these concepts, Pierre Wantzel ( 1837 ) proved that straightedge and compass alone cannot trisect an arbitrary angle nor Hermite showed that a straightedge and compass quadrature of the circle ( construction of a square equal in area to a given circle ) was also impossible by proving that [ [ Pi | ] ] is a transcendental number.
