This heart-shaped acrylic puzzle has 3 objectives. To solve them, begin by laying out all elements on a table.
Task 1: Using all five elements of the set, make different silhouettes as pictured in the instructions. Elements can be flipped and turned, but they must not overlap. You can make more than 100 different symmetrical polygons with different number of angles. The hardest one to make seems to be a polygon with 13 angles.
Task 2: Using all five elements of the set, make two congruent shapes simultaneously (ie. equal in form and size). There are 2 solutions.
Task 3: Prove that using this set of elements one can tile an infinite plane.
