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.(adsbygoogle = window.adsbygoogle || []).push({});

- I dont 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 dont 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.

- ???
