# RD Sharma Solutions Class 12 Relations

In class XI, we have already learned about the notion of a relation, its domain, co-domain and range. If R is a relation from set A to a set B and (a,b) $\epsilon$ R, then we say that a is related to b under relation R and we write as a R b. A relation can be represented in rooster or tabular form. In this chapter, we will discuss different types of relation. Some of the relations are void, universal and identity relations. Get clear ideas about the reflexive relation, symmetric relation, transitive relation and antisymmetric relation. Various properties are covered with several examples so that one can easily identify the type relation and where to apply each property.
