 Vertex[ <Conic> ]
 Returns (all) vertices of the conic section.
 Vertex[ <Inequality> ]
 Returns the points of intersection of the borders.
 Example:
Vertex[(x + y < 3) && (x  y > 1)]
returns point A = (2, 1).{Vertex[(x + y < 3) ∧ (x  y > 1) && (y >  2)]}
returns list1 = {(2, 1), (5, 2), (1, 2)}.Vertex[(y > x²) ∧ (y < x)]
returns two points A = (0, 0) and B = (1, 1).{Vertex[(y > x²) ∧ (y < x)]}
returns list1 = {(0, 0), (1, 1)}.
 Vertex[ <Polygon> ]
 Returns (all) vertices of the polygon.
 Vertex[ <Polygon>, <Index> ]
 Returns nth vertex of the polygon.
Note: To get the vertices of the objects polygon / conic / inequality in a list, use
{Vertex[Object]}
.
Following text is about a feature that is supported only in GeoGebra 5.0.
Note: From GeoGebra 5, this command will work with 3D objects as well.
