Right Triple Convexity
Journal of convex analysis, Tome 23 (2016) no. 4, pp. 1219-1246
A set M in Rd is rt-convex if every pair of its points is included in a 3-point subset {x,y,z} of M such that the triangle with the corners x, y and z has a right angle at y. We characterize rt-convex sets, and for 2-connected polygonally connected sets, for 3-connected sets, for geometric graphs, and for finite sets.
