In geometry, a vertex (plural vertices) is a special kind of point that describes the corners or intersections of geometric shapes.
In a polygon, a vertex is called  convex  if the internal angle of the polygon, that is, the angle formed by the two edges at the vertex, with the polygon inside the angle, is less than Ï radians (180Â°, two right angles) ; otherwise, it is called concave or reflex.
