- 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 n-th 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.
