name: label: maker
content: Wheeler, Albert Harry
notes: label: Description
content: This hinged dissection has nine pieces which may be arranged to form one large square or three smaller ones of differing size. The area of the green pieces(arranged as a square) equals the area of the yellow and brown pieces (arranged as a square). The four green pieces are hinged together, as are the four yellow pieces.
