  2. Tangent lines to circles - Wikipedia

    en.wikipedia.org/wiki/Tangent_lines_to_circles

    A new circle C 3 of radius r 1 − r 2 is drawn centered on O 1. Using the method above, two lines are drawn from O 2 that are tangent to this new circle. These lines are parallel to the desired tangent lines, because the situation corresponds to shrinking both circles C 1 and C 2 by a constant amount, r 2 , which shrinks C 2 to a point.

  3. Exsecant - Wikipedia

    en.wikipedia.org/wiki/Exsecant

    The external secant or external distance of a curved track section is the shortest distance between the track and the intersection of the tangent lines from the ends of the arc, which equals the radius times the trigonometric exsecant of half the central angle subtended by the arc, ⁡. [12] By comparison, the versed sine of a curved track ...

  4. Osculating circle - Wikipedia

    en.wikipedia.org/wiki/Osculating_circle

    For a curve C given by a sufficiently smooth parametric equations (twice continuously differentiable), the osculating circle may be obtained by a limiting procedure: it is the limit of the circles passing through three distinct points on C as these points approach P. [3]

  5. Circle packing theorem - Wikipedia

    en.wikipedia.org/wiki/Circle_packing_theorem

    Set the new radius for v to be the value for which k circles of radius r would give a covering angle of exactly 2π. Each of these steps may be performed with simple trigonometric calculations, and as Collins and Stephenson argue, the system of radii converges rapidly to a unique fixed point for which all covering angles are exactly 2π.

  6. Incircle and excircles - Wikipedia

    en.wikipedia.org/wiki/Incircle_and_excircles

    [3] The center of the incircle, called the incenter, can be found as the intersection of the three internal angle bisectors. [3] [4] The center of an excircle is the intersection of the internal bisector of one angle (at vertex A, for example) and the external bisectors of the other two.
