Consider the relation perpendicular on a set of lines in a plane. Show that this relation is symmetric and neither reflexive and nor transitive

Give an example of a relation which is symmetric but neither reflexive nor transitive.

Let L be the set of all lines in a plane and R be the relation in L defined as R={(L_1,L_2):L_1 (is perpendicular to L_2 } Show that R is symmetric but neither reflexive nor transitive.

Give an example of a relation which is symmetric and transitive but not reflexive.

In the set of straight lines in a plane, for the relation 'perpendicular' check whether it is reflexive, symmetric and transitive.

Give an example of a relation which is transitive but neither reflexive nor symmetric.

Every relation which is symmetric and transitive is also reflexive.

An integer m is said to be related to another integer n if m is a multiple of n . Check if the relation is symmetric, reflexive and transitive.
