Show that the relation R detained by (a, b) R (c, d)  a + b = b + c on the set N × N is an
equivalence relation.
Prove that the relation R in the set A = {1, 2, 3, 4, 5} given by R = {(a, b) : |a – b| is even}
is an equivalence relation.
Show that the relation S in the set A = {x  z : o  x  12} given by S = {(a, b) : a, b  z |a – b| is
divisible by 4} is an equivalence relation. Find the set of all elements related to 1.
If R1 and R2 are two equivalence relations in a given set A, show that R1  R2 is also an
equivalence relation.
