vertex
含义: The point where two or more lines, edges, or curves meet to form an angle, or the highest point of a shape or structure.
In geometry, vertex refers to the corners of polygons and polyhedra, as well as the turning point of a parabola. In graph theory, vertices (also called nodes) are the fundamental units connected by edges. The plural is vertices in formal mathematical usage, though vertexes is occasionally seen. The word also carries a figurative sense of the peak or summit of something.
