Participation Question 1

What are the complications that you can imagine that results from including the points on the side of the triangle in the triangle or not?

Hint: Two triangles that share a border may have problems.

If the triangles share a border, then you will have to decide whether points on the border belong to one or the other. I think there might need to be some kind of average function or something that decides how different values might be reconciled, but I think omitting the border from either might also not be the right solution because you really don't want there to be a gap.

Participation Question 2

When d11 * d22 - d12 * d12 = 0, the system will have no solution. When might this happen, and what does it mean?
