1. The problem statement, all variables and given/known data R is the relation of the set R; xRy if and only if (x + y)2 = 1. Is it transitive. 2. Relevant equations 3. The attempt at a solution Every description of transitive involves 3 elements. Here, I just have x and y. It is defined as xRy so there is a relation but is it transitive all by itself with just those two elements?
