圆的英文读circle。

当一条线段绕着它的一个端点在平面内旋转一周时，它的另一个端点的轨迹叫做圆。

在同一平面内，到定点的距离等于定长的点的集合叫做圆。

圆是一种几何图形。根据定义，通常用圆规来画圆。  同圆内圆的半径长度永远相同，圆有无数条半径和无数条直径。圆是轴对称、中心对称图形。对称轴是直径所在的直线。  同时，圆又是“正无限多边形”，而“无限”只是一个概念。当多边形的边数越多时，其形状、周长、面积就都越接近于圆。所以，世界上没有真正的圆，圆实际上只是概念性的图形。

在同一平面内到定点的距离等于定长的点的集合叫做圆（circle）。这个定点叫做圆的圆心。

圆形一周的长度，就是圆的周长。能够重合的两个圆叫等圆。

圆是一个正n边形（n为无限大的正整数），边长无限接近0但永远无法等于0。

1.连接圆心和圆上的任意一点的线段叫做半径，字母表示为r（radius）

2.通过圆心并且两端都在圆上的线段叫做直径，字母表示为d（diameter）。直径所在的直线是圆的对称轴。

圆的直径 d=2r。
