... exactly one point, called the point of tangency. There are important relationships involving tangents. A common tangent is a line, ray, or segment that is tangent to two circles in the same plane. • A line is tangent to a circle if and only if it is perpendicular to a radius at a point of tangency. ...

... orientation on γ2 , then the angles between the oriented tangents to γ1 and γ2 will be replaced by the supplementary angles and will take values in the interval [0, π/2 + ε]. Remarks. 1. Thus, for immersed oriented curves γ1 , γ2 : [0, 1] R3 , we can only state that there exist orthogonal orient ...

Riemannian connection on a surface

For the classical approach to the geometry of surfaces, see Differential geometry of surfaces.In mathematics, the Riemannian connection on a surface or Riemannian 2-manifold refers to several intrinsic geometric structures discovered by Tullio Levi-Civita, Élie Cartan and Hermann Weyl in the early part of the twentieth century: parallel transport, covariant derivative and connection form . These concepts were put in their final form using the language of principal bundles only in the 1950s. The classical nineteenth century approach to the differential geometry of surfaces, due in large part to Carl Friedrich Gauss, has been reworked in this modern framework, which provides the natural setting for the classical theory of the moving frame as well as the Riemannian geometry of higher-dimensional Riemannian manifolds. This account is intended as an introduction to the theory of connections.
