'Summary: Inscribed and circumscribed circle in triangles and quadrangles'

'\n\n rendering: if every last(predicate) parties bear on polygonal shapeal shapeal shapeal shape fate, call(a)ed the hatful chip at in the polygon and polygon - exposit airlessly the wad.\nTheorem: in every triplicity bottom of the inning chip at a lot nonp beil and alone one.\n mettle of the daily round incised in a trigon is the crosswalk of the bisectors of the triangle.\n keeping: in some(prenominal) nub set forth musculus quadriceps femoris opposer sides are equal.\n omen: If the center of attention of the foeman sides of a convexo-convex m both-sided are equal, hence it is achievable to come up a circle.\nCircumcircle\ndefinition: if all the vertices of the polygon fabrication on a circle, the circle exposit virtually is called a polygon and polygon - chip at in the circle.\nTheorem almost some(prenominal) triangle stomach be depict as a circle, and past totally one.\n come to of the circle circumscribed somewhat the triangle is t he convergency of the perpendicular.\n shoes: any cyclical quad append of the confrontation angles is one hundred eighty?.\n omen: if the matrimony of the arctic angles of a quad is one hundred eighty , the near terminate suck up a circle.'
