Describe an algorithm that computes the convex hull of P in O(n). 4. Using Eulers formula as a starting point, prove the following inequalities for a planar graph with the additional property that each vertex has degree greater than or equal to 3; a. e v 3 2 b. 6 3 f e c. e f 3 2 d. 6 3 v e e. 4 2 f v f. 4 2 v f Also prove that if a planar graph is triangulated (that is every face is a triangle. Note in this case some vertices may have degree less than 3) then 6 3= v e ....
