What is the least number of points in which two triangles can intersect?

There are two ways to think of this question, if the triangles don't have to intersect then the answer is zero. If the triangles have to intersect, then the minimum number of points is one, if the triangles meat at vertex to edge or vertex to vertex.


How many sides does a vertex have?

A vertex is a point and so does not have any sides. In 2-dimensional space, there must be at least 2 lines meeting at a vertex and in 3-dimensional space, there must be at least 3 planes.

What is vertex cover problem?

A vertex cover of a graph is a set of vertecies where every edge connects to at least one vertex in the set.As a concrete example, a student club where if any two students are friends, then at least one is in the club.Suppose the school has three students, A, B, and C. A and B are friends and A and C are friends, but B and C are not friends. One obvious vertex cover would be to have all the students in the club, {A.B.C}. Another would be just {B,C}. Another would be just {A}.{B} would not be a vertex cover, since A and C are friends, but neither is in the club.The optimal vertex cover is the smallest possible vertex cover. In the school friends example, {A} is the optimal vertex cover. In general, the opitmal vertex cover problem is NP-complete, which makes it a very difficult problem for large groups, and interesting problem in computer science.
