In terms of polynomials (I can't think of how to applied this to sets) a "like" term is a comparison between two terms of the polynomial. For example, consider the two polynomials \(\displaystyle 3x^2 + 2x - 3\) and \(\displaystyle 5x^3 - 3x + 7\). The like terms are the terms that are in both polynomials. Here the there is only one like term: the one in x. (I suppose you could call the constant terms "like" as they are both terms in \(\displaystyle x^0\) but I don't think anyone does this.)
