  2. The "feet" on the first design suggest that there are at least two pieces shaped like this:



  3. The "stem" on the second design suggests at least one piece shaped like this:

Solution

The centers of the circles for the two arcs are at points A and B. The radii of the arcs are the same length as the radius of the original circle.
