To determine if a set of points in the plane are the vertices of a convex polyhedron, you can follow these general steps:
1. **Check Convexity**: A polyhedron is convex if, for any two points within it, the straight line connecting them is also completely within the polyhedron. To check this, you would need to ensure that the interior angles of any triangle formed by three points (which are supposed to be vertices) do not exceed 180 degrees.
2. **Valid Faces**: Ensure that each face of the polyhedron is a convex polygon. This means that no interior angle of any face exceeds 180 degrees.
3. **Non-coplanar Points**: The points should not all be coplanar. If they are, you would not have a polyhedron, but a polygon or a point.
4. **No Coincident Vertices**: The points should not be coinc
