Determine whether the relations represented by the directed graphs shown in 27 and 28 are reflexive, irreflexive, symmetric, antisymmetric, asymmetric, and/or transitive. (graphs are in the attachment if you can't see it below)
Are both of the graphs, reflexive, symmetric, and transitive?
In graph 28, the left most point on the top is missing it's letter, which is the letter a.
"Reflexive" requires that any member of the set be related to it self. That is signaled in the graphs you show by a loop from point x back to that same point. That is Plato's point.
