Answer :
It should be noted that a relation that's both symmetric and antisymmetric is R = {a, b) | a= b}.
What is a relation?
A relation in mathematics simply means the relationship between two or more variables.
In this case, the relation that's both symmetric and antisymmetric is R = {a, b) | a= b}.
On the other hand, a relation on a set that is neither symmetric nor antisymmetric will be R = {a, b) | a < = b}
This is not symmetric because a < b and v < a can never be butt true.
