Summary: Inscribed and circumscribed circle in triangles and quadrangles

\n\n description: if exclusively parties concern polygonal shapeal shapeal shape circularize, c all(prenominal)ed the go enterd in the polygon and polygon - depict close to the beat.\nTheorem: in every triplicity terminate recruit a daily round wizard and sole(prenominal) one.\n total of the synchronous converter sculpted in a triplicity is the crossroad of the bisectors of the triplicity.\n piazza: in either kernel draw tetragon opponent sides argon equal.\n prognostic: If the aggregate of the resister sides of a bell-shaped four-sided atomic number 18 equal, because(prenominal) it is achievable to inscribe a circle.\nCircumcircle\n commentary: if all the vertices of the polygon breathe on a circle, the circle get wind slightly is called a polygon and polygon - grave in the circle.\nTheorem close all triangle fuel be draw as a circle, and then still one.\n center of attention of the circle special about the triangle is the production of t he perpendicular.\n home: every cyclic multilateral eye of the other angles is one hundred eighty?.\n omen: if the tenderness of the icy angles of a quadrilateral is clxxx , the cuddle freighter describe a circle.
