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 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 — 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

Lower tangent arc — A lower tangent arc is a rarely observable halo, an optical phenomenon appearing under and tangent to a 22° halo centred around the sun.Just like upper tangent arcs, the shape of a lower tangent arc is dependent on the altitude of the sun. As the … Wikipedia
Upper tangent arc — An upper tangent arc is a halo, an atmospheric optical phenomenon which appears over and tangent to the 22° halo centred around the sun.The shape of an upper tangent arc varies with the elevation of the sun; while the sun is low (less than… … Wikipedia
Coxeter's loxodromic sequence of tangent circles — Blue circle 0 is tangent to circles 1, 2 and 3, as well as to preceding circles −1, −2 and −3. In geometry, Coxeter s loxodromic sequence of tangent circles is an infinite sequence of circles arranged such that any four consecutive circles in the … Wikipedia
Monge's theorem — In geometry, Monge s theorem, named after Gaspard Monge, states that for any three circles in a plane, none of which is inside one of the others, the three intersection points of the three pairs of external tangent lines are in fact collinear.… … Wikipedia
