This article is about GeoGebra command.

Command Categories (All commands)


Vertex[Conic]
Returns (all) vertices of the conic section.
 Following text is about a feature that is supported only in GeoGebra 4.2.


Vertex[ <Inequality> ]
Returns the points of intersection of the borders
Example:
Vertex[(x + y < 3) && (x - y > 1)] returns point (2,1) ;
{Vertex[(x + y < 3) ∧ (x - y > 1)&& (y>-2)]} returns list {(2, 1), (5, -2), (-1, -2)}
{Vertex[(y > x²) ∧ (y < x)]} returns list {(0, 0), (1, 1)}.


Vertex[Polygon]
Returns (all) vertices of the polygon.
Vertex[Polygon, Number n]
Returns n-th vertex of the polygon.
Note: To get vertices of the polygon / conic as list, use {Vertex[t]}.
