Let be a line. Let be two points so that not lies on , lies on , and perpendicular to . Let be any other line who meets in .In a hyperbolic geometry, as moves off to infinity along the line meets the line which is said to be parallel to . The angle is called the angle of parallelism for perpendicular distance , and is given by
which is called Lobachevsky’s formula.
