TETIVNI ČETVEROKUTI
ТЕТИВНИ ЧЕТИРИАГОЛНИЦИ
|
Obitelj je četverokuta vrlo velika. Neke njezine članove kao što su kvadrat, pravokutnik i paralelogram već ste dobro upoznali. Ovdje ćemo opisat jednog manje poznatog pripadnika te obitelji: tetivni četverokut.
Tetivni četverokut je četverokut oko kojeg se može opisati kružnica.

Incircle of the arbelos
|
Let C be a point on a segment AB. The region bounded by the three semicircles (on the same side of AB) with diameters AB, AC and CB is called an arbelos. Suppose the smaller semicircles have radii a and b respectively. Let D be the intersection of the largest semicircle with the perpendicular through C to AB. This perpendicular is an internal common tangent of the smaller semicircles. |

Inversion in a circle | Инверзија
|
Take a fixed circle K in the plane, with center O and radius R. The inversion in K sends every point P (other than O) to the point P′ on the ray OP determined by the condition OP′ · OP = R2 . We call P′ the inversive image of P in K, or simply the inverse. |
