solution:
R = {(P, Q): distance of the point P from the beginning is equivalent to the distance of the point Q from the origin}
Say “O” is beginning Point.
Since the distance of the point P from the beginning is consistently equivalent to the distance of a similar point P from the beginning.
Operation = OP
So (P, P) R. R is reflexive.
Distance of the point P from the beginning is equivalent to the distance of the point Q from the beginning
Operation = OQ then OQ = OP
R is symmetric.
Likewise OP = OQ and OQ = OR then, at that point OP = OR. R is transitive. Subsequently, R is a comparable connection.
