Problems of Geometric Combinatorics

Cut along the solid lines to make puzzle pieces.
Assemble the pieces in the form of a hexagon so the
symbols at each vertex on/within the hexagon match.
Each problem has a unique solution.

Email me if you give up and want the solution for one of the other problems.
This paper describes how I constructed these problems.

Below is an example illustrating the solution for a smaller problem that involves just 6 puzzle pieces.
