The only two lines asymptotic to R through P are x and y. All other lines through P not intersecting R , with angles greater than θ with PB , are called ultra-parallel ( or disjointly parallel ) to R. Notice that since there are an infinite number of possible angles between θ and 90 ° , and each one will determine two lines through P and disjointly parallel to R , there exist an infinite number of ultraparallel lines .
