R = {( x,y) : x is father of y}

Reflexive ~ XA

(X,X) not belong to R

X IS NOT FATHER OF Himself.

So,R is not reflexive.

Symmetric ~ Let(X,y) A

(X,Y) R

X is Father of Y.

But Y is Not Father of X.

So, (Y,X) not belong to R.

R is not symmetric.

Transative ~ Let (X,Y,Z) R

(X,Y) R (Y,Z) R

X is Father of Y. Y is Father of Z.

But X is not Father ofZ.

(X,Z) Not belong to Z.

So, R is not transative


( this sing is belong to)

R Meaning is Real number.
