If ‘a’ is “perpendicular to” ‘b’ is denoted by a $ \perp $ b, then we have p $ \perp $ q, q $ \perp $ p, m $ \perp $ p, p $ \perp $ m, m $ \perp $ n, n $ \perp $ m, n $ \perp $ q, q $ \perp $ n.
$ \therefore $ In the roster form, the relation ‘is perpendicular’ is given by
‘$\perp $’ = {(p, q), (q, p), (m, p), (p, m), (m, n), (n, m), (n, q), (q, n)}
