Tangent lines to circles — In Euclidean plane geometry, tangent lines to circles form the subject of several theorems, and play an important role in many geometrical constructions and proofs. Since the tangent line to a circle at a point P is perpendicular to the radius to … Wikipedia
Tangent — For the tangent function see trigonometric functions. For other uses, see tangent (disambiguation). In geometry, the tangent line (or simply the tangent) to a curve at a given point is the straight line that just touches the curve at that point… … Wikipedia
Tangent cone — In geometry, the tangent cone is a generalization of the notion of the tangent space to a manifold to the case of certain spaces with singularities. Definition in convex geometry Let K be a closed convex subset of a real vector space V and part;… … Wikipedia
Tangent circles — In geometry, tangent circles (also known as kissing circles) are circles that intersect in a single point. There are two types of tangency: internal and external. Many problems and constructions in geometry are related to tangent circles; such… … Wikipedia

Tangent developable — The tangent developable of a space curve gamma(t) is a ruled surface of the form gamma(t)+s gamma^prime(t). Intuitively it is the union of the tangent lines to the curve. A result of Euler states that most developable surfaces can be obtained as… … Wikipedia
tangent line — In geometry, a line that intersects a circle exactly once; in calculus, a line that touches a curve at one point and whose slope is equal to that of the curve at that point. Particularly useful as approximations of curves in the immediate… … Universalium
