A relation R in a set A is called reflexive, if (a, a) belongs to R, for every 'a' that belongs to A.
Example :
R : {1, 2, 3} -> {1, 2, 3} = { (1, 1), (2, 2), (3, 3) } is a reflexive relation.
R : {1, 2, 3} -> {1, 2, 3} = { (1, 1), (2, 2) } is NOT a reflexive relation.
Example :
R : {1, 2, 3} -> {1, 2, 3} = { (1, 1), (2, 2), (3, 3) } is a reflexive relation.
R : {1, 2, 3} -> {1, 2, 3} = { (1, 1), (2, 2) } is NOT a reflexive relation.
