Make A Square
Made by interlocking Puzzles 2000.
(directions card and 6 identical Zebrawood pieces, each 2.25 inches)
Here is what Interlocking Puzzles said:
"There are at least eighteen different challenges requiring the special angles
and three, four, five, or six pieces of our Make a Square puzzle.
Geometric shapes possible include triangles, squares, rectangles, pentagons, hexagons, parallelograms, and trapezoids.
This tiling puzzle seems simple, but it is quite challenging to find all the solutions.
These 6 pieces are each over 2 inches long, which allows the largest finished shape to be over 7 inches across the diagonal."
