vertex
英 ['vɜːteks]
美 ['vɝtɛks]
助记提示
1、vert- + -ex.
2、字面含义：that which turns, the turning point. => whirling column, whirlpool. => highest point, the point opposite the base in geometry.
3、其原始含义或者说最初含义为：whirling column, whirlpool. 也就是：漩涡，漩涡所涌出的漩涡柱；想象一下升起的漩涡柱顶端的顶点。再想象一下咱们物理学中的“钟摆模型”，其自由转动只会低于其中心的转动点。
4. 转折点---顶点就是发生转折的点。
