points ‘x’ on every line segment possible that joins 2 points from within the set is a convex set. x1 and x2 has to belong to the set S and also belong to a n-dimensional space, since the set S could be in any dimension (2-D, 3-D and so on). The expression involving λ and 1-λ is also called “convex
