There are two such external tangent lines for any two circles. Each such pair has a unique intersection point in the projective plane. Monge's theorem states that the three such points given by each circle are always in a straight line. In the case of two of the circles being of equal size, the two external tangent lines are parallel. In this case Monge's theorem asserts that the other two intersection points must lie on a line parallel to those two external tangents. In other words if the two external tangents are considered to intersect at the point at infinity, then the other two intersection points must be on a line passing through the same point at infinity, so the line between them takes the same angle as the external tangent."@en }
