Question 2c

By Krista Floer

What happens when Barney starts at a trisection point?

Using the proof here, we can show that Barney will still travel the length of the perimeter of triangle ABC. The proof is very similar for this case as it is for the general case, so it is left to the reader.

It looks like all of the small triangles in triangle ABC are congruent. This proof is in the answer to this question.
