What are verticiies?

Answer 1

Vertices are the plural of vertex, which refers to the points where two or more lines, edges, or rays meet in geometry. In the context of shapes, such as polygons or polyhedra, vertices are the corner points that define the shape's structure. For example, a triangle has three vertices, while a cube has eight. In graph theory, a vertex represents a node in a graph, connecting edges to other vertices.
