Transitive relations space binary relations identified on a collection such that if the first element is related to the 2nd element, and the 2nd element is pertained to the 3rd element the the set, climate the very first element have to be pertained to the third element. For example, if for three facets a, b, c in set A, if a = b and b = c, climate a = c. Here, equality '=' is a leg relation. There are greatly three varieties of relationships in discrete mathematics, specific reflexive, symmetric and transitive relations among many others.
You are watching: If a equals b and b equals c then a equals c
In this article, we will explore the ide of transitive relations, the definition, nature of transitive connections with the assist of some instances for a far better understanding that the concept.

Transitive relations are binary relationships in collection theory that are characterized on a collection B such that element a must be related to element c, if a is regarded b and also b is regarded c, because that a, b, c in B. To recognize this, let us consider an example of transitive relations. Define a relation R ~ above the collection of integers Z as aRb if and also only if a > b. Now, assume because that integers a, b, c in Z, aRb and also bRc ⇒ a > b and also b > c. We understand that for integers, whenever a > b and b > c, we have a > c which suggests a is pertained to c, that is, aRc. Hence, R is a transitive relation.
Transitive relationships Definition
A binary relationship R defined on a collection A is said to be a transitive relationship for all a, b, c in A if a R b and also b R c, then a R c, that is, if a is pertained to b and b is pertained to c, then a must be pertained to c. Mathematically, we have the right to write the as: a relationship R defined on a set A is a transitive relation for all a, b, c ∈ A, if (a, b) ∈ R and also (b, c) ∈ R, then (a, c) ∈ R.
Let us see some meanings of relationships that are pertained to transitive relations:Anti-transitive Relation - A binary relationship R identified on a set A is one anti-transitive relation for a, b, c in A if (a, b) ∈ R and (b, c) ∈ R, climate this constantly implies the (a, c) ∈ R does not hold.Intransitive Relation - A binary relation R defined on a collection A is one intransitive relation for some a, b, c in A if (a, b) ∈ R and (b, c) ∈ R however (a, c) ∉ R.
Now, that we have studied the meaning of transitive relations, let us go through some mathematical too non-mathematical examples of transitive connections for a better understanding.'is a subset of' is a transitive relation characterized on a power collection of sets. If A is a subset that B and also B is a subset of C, then A is a subset of C.'Is a organic sibling' is a leg relation as if one human A is a biological sibling of an additional person B, and B is a biological sibling the C, climate A is a organic sibling that C.'Is equal to (=)' is a transitive relation identified on a set of numbers. If a = b and also b = c, then a = c.
Let us discover some properties of leg relations:The train station of a transitive relationship is a transitive relation. Because that example, together we discussed above 'is less than' is a leg relation, then the converse 'is greater than' is additionally a transitive relation.The union of two transitive relations require not it is in transitive. For example, mean R and S room transitive connections such that (x,y) is in R, and also (y,z) is in S, yet (x,z) is in neither.The intersection of 2 transitive connections is a leg relation. Because that example, 'is better than or equal to' and 'is same to' space transitive relations and their intersection relation is 'is equal to' i beg your pardon is a transitive relation.A transitive relation is an asymmetric relationship if and only if that is irreflexive.
Important notes on transitive RelationsA relation characterized on an empty set is constantly a leg relation.There is no fixed formula to identify the number of transitive relations on a set.The match of a leg relation require not be transitive.

Example 1: define a relation R on a set A = a, b, c as R = (a, b), (b, c), (b, b). Recognize if R is a transitive relation.
Solution: together we deserve to see that (a, b) ∈ R and (b, c) ∈ R, and also for R to be transitive (a, c) ∈ R need to hold, yet (a, c) ∉ R.
So, R is not a leg relation.
Answer: R is not a leg relation
Example 2: inspect if 'is parallel to' identified on a collection of lines is a transitive relation.
Solution: We recognize that if heat 1 is parallel to line 2 and line 2 is parallel to heat 3, climate line 1 is parallel to line 3 as lines parallel come the exact same line space parallel to every other.
Answer: 'Is parallel to' is a transitive relation.
