595. Polygon with 8 sides

Easy Medium Hard Extreme

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.
