In a set of ants in a locality, two ants are said to be related iff they walk on a same straight line, then the relation is

X is the set of all residents in a colony and R is a relation defined on X as follows: ''Two persons are related iff they speak the same language'' The relation R, is

X is the set of all residents in a colony and R is a relation defined on X as follows: ''Two persons are related iff they speak the same language'' The relation R, is

If R is a relation defined as aRb, "iff"|a-b|gt0 , then the relation is

Let L be the set of all straight lines in the Euclidean plane. Two lines l_(1)" and "l_(2) are said to be related by the relation R" iff "l_(1) || l_(2) . Then the relation R is :

When a relation R on a set A is said to be reflexive

Let L be the set of all straight lines in the Euclidean plane. Two lines l_(1) and l_(2) are said to be related by the relation R iff l_(1) is parallel to l_(2) . Then, the relation R is not

Let L be the set of all straight lines in the Euclidean plane. Two lines l_(1) and l_(2) are said to be related by the relation R iff l_(1) is parallel to l_(2) . Then, the relation R is not

Let L be the set of all straight lines in the Euclidean plane. Two lines l_(1) and l_(2) are said to be related by the relation R iff l_(1) is parallel to l_(2) . Then, check the relation is reflexive , symmetric or transitive
