 We prove that a nonempty closed and geodesically convex subset of the lplane R2is hyperconvex and we characterize the tight spans of arbitrary subsets of R2via this property: Given any nonempty X R2, a closed, geodesically convex and minimal subset Y R2containing X is isometric to the tight span T(X) of X.
