Why is a Milk Carton an example of a nonconvex polyhedron such that the sum of the face angles around each vertex is no more than 360 degrees.
- I don't know how a milk carton qualifies as a nonconvex polyhedron. isn't every face a convex polygon?
Is it possible to have a polyhedron with 7 edges? Why or why not?
- I suspect it's not possible, but I can't 100% justify why not. I tried arguing that it's impossible to have a polyhedron with 7 edges because every face must be a polygon, but i don't know how to finish that statement.
Given a vertice v and a winged edge data structure, describe how to create a sorted list of all edges incident to v.
