Nine o'clock round

九点圆

Nine rounds (also known as Euler round, Feuerbach round), in the plane geometry, for any triangle, nine o'clock through the triangular triangle of the midpoint, three high foot, and the vertex to the heart of the three lines Of the midpoint. Nine-point round theorem points out that for any triangle, this nine must be round. And the nine-point circle has the following properties: ▪ The radius of the nine-point circle is half of the circumcircle and the point at which the nine-point circle is divided into any point on the circumscribed circle. ▪ The center of the circle is on the Euler line and at the midpoint of the center line. ▪ Nine-point circle and triangular inscribed circle and tangent circle tangent (Feuerbach theorem). ▪ Four o'clock on the circumference to take three points to make triangles, four triangles of the nine-point circle of the heart round (Kulwich - big upper theorem). ... 九點圓(又稱歐拉圓費爾巴哈圓),在平面幾何中,對任何三角形,九點圓通過三角形三邊的中點、三高的垂足、和頂點到垂心的三條線段的中點。九點圓定理指出對任何三角形,這九點必定共圓。而九點圓還具有以下性質: ▪ 九點圓的半徑是外接圓的一半,且九點圓平分垂心與外接圓上的任一點的連線。 ▪ 圓心在歐拉線上,且在垂心到外心的線段的中點。 ▪ 九點圓和三角形的內切圓和旁切圓相切(費爾巴哈定理)。 ▪ 圓周上四點任取三點做三角形,四個三角形的九點圓圓心共圓(庫利奇-大上定理)。...
