US 名圆, 圆圈 维圆
- 圆是一種几何图形，指的是平面中到一个定点距离为定值的所有点的集合。这个给定的点称为圆的圆心。作为定值的距离称为圆的半径。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就是一个圆。根据定义，通常用圆规来画圆。
- 圆作为一条闭合的曲线，将平面分为两个部分，即圆的内部和圆的外部。日常生活中的圆既可以指作为边界的曲线（这时也称为圆周），也可以指这条曲线以及它内部的部分的总和（这时也称为圆盘）。圆周的长度称为圆的周长。
- 圆是特殊的椭圆，所以是圆锥曲线的一种。当椭圆的离心率等于0，也就是说两个焦点重合时，就是一个圆。换句话说，圆是用垂直于圆锥对称轴线的平面截取圆锥所得到的平面曲线。
