# 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?**
