Shown above is a seven sided convex polygon built from 2 squares and 3 triangles. 12 matchsticks were used to achieve this. The outside angles are all greater than 180 degrees as illustrated with angle "a" above.
Create your own convex polygon. The following rules apply:
1. Polygon must have 8 sides
2. 17 matchsticks to be used
3. All outside angles to be greater than 180 degrees
4. There must be 6 equal sized triangles
5. There must be 2 equal sized squares
6. All matchsticks must be flat on the surface.
i belive this would be much cooler if the solution was used to explain the principle of the puzzle and the example configuration at the beginning was the solution the problem: 7 sides, konvex shape, 2 squares, 3 triangles, 12 matchsticks to be used
