Construction of the circumcircle (red) and the circumcenter Q(red dot)

在数学中,一个二维平面上的多边形的外置圆是一个使得该多边形的所有顶点都在其上的圆形,这时称这个多边形为圆内接多边形,外置圆的圆心被称为该多边形的外心。

一个多边形至多有一个外置圆,也就是说对于一个多边形,它的外置圆,如果存在的话,是唯一的。并非所有的多边形都有外置圆。三角形和正多边形一定有外置圆。拥有外置圆的四边形被称为圆内接四边形。

Construction of the circumcircle (red) and the circumcenter Q(red dot)
Alternate construction of the circumcenter (intersection of broken lines)

In geometry, the circumscribed circle or circumcircle of a polygon is a circle which passes through all the vertices of the polygon. The center of this circle is called the circumcenter and its radius is called the circumradius.

A polygon which has a circumscribed circle is called a cyclic polygon (sometimes a concyclic polygon, because the vertices are concyclic). All regular simple polygons, all isosceles trapezoids, all triangles and all rectangles are cyclic.
