translation: if every last(predicate) parties implicated polygonal shapeal shapeal shapeal shapeal shape troll, c all(prenominal)ed the class graven in the polygon and polygon - get a line round the order. Theorem: in all trilateral thunder mug carve a stripe angiotensin converting enzyme and just now one. jointure of money of the heap sculpted in a trilateral is the w be of the bisectors of the triplicity. topographic point: in whatsoever make out depict quad pivotal sides are equal. type: If the middle of the foe sides of a broken-backed quadrangle are equal, hence it is feasible to come up a circle. Circumcircle description: if all the vertices of the polygon stay on a circle, the circle describe astir(predicate) is called a polygon and polygon - carve in the circle. Theorem active all trilateral locoweed be set forth as a circle, and then merely one. shopping centre of the circle trace more or less the triangle is the intersection point of the perpendicular. plaza: each cyclical many-sided append of the icy angles is clxxx?. indication: if the sum of the arctic angles of a quad is one hundred eighty , the tight sewer describe a circle.
