what are vertices in math

In mathematics, a vertex (plural: vertices) is a point where two or more line segments or edges meet, like a corner. For example, a cube has 8 vertices, and a cone has one vertex. Edges are the line segments that join one vertex to another and are also where the shape’s faces meet. Faces are the individual flat surfaces of a solid object. The relation between vertices, faces, and edges can be easily determined with the help of Euler’s Formula, which states that the number of faces plus the number of vertices minus the number of edges always equals 2.
