History of the Problem:
- This problem was an exercise that was found
in the text Introduction to Geometry by Coxeter.
The exploration of the problem's solution was initially done
in Geometer's Sketchpad (GSP). Searching for other means
of a solution, we tried other methods of approaching the problem,
which led us to road blocks! We have two ways to work this
problem and are currently searching for other approaches.
