Topics Covered in Exercise 1.1 Class 12 Mathematics Questions
Ex 1.1 class 12 maths solutions comes with a topic of types of relations. This topic is elaborated in detail by the expert faculty of eSaral.
1. 
Types of Relations 

Types of Relations  A relation R that exists between A and A can also be expressed as a relation on A. In other words, a relation in a set A is a subset of A × A. Therefore, two extreme relations are A × A and the empty set φ.
Here are the definitions of different type of relation which are given below:

Empty Relation  A relation R in a set A is called empty relation, if no element of A is related to any element of A, i.e., R = $\phi$ ⊂ A × A.

Universal Relation  A relation R in a set A is called universal relation, if each element of A is related to every element of A, i.e., R = A × A.
Both the empty relation and the universal relation are sometimes called trivial relations.

Reflexive Relation  A relation R in a set A is called reflexive, if (a, a) ∈ R, for every a ∈ A.

Symmetric Relation  A relation R in a set A is called symmetric, if (a_{1} , a_{2 }) ∈ R implies that (a_{2} , a_{1} ) ∈ R, for all a_{1} , a_{2 }∈ A.

Transitive Relation  A relation R in a set A is called transitive, if (a_{1} , a_{2} ) ∈ R and (a_{2} , a_{3} ) ∈ R implies that (a_{1} , a_{3} )∈ R, for all a_{1 }, a_{2} , a_{3} ∈ A.

Equivalence Relation  A relation R in a set A is said to be an equivalence relation if R is reflexive, symmetric and transitive.
