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