Puzzle forming regular geometric figures from a changeable number of pieces having sequentially increasing surface areas
Abstract
Abstract A PUZZLE HAVING A SET OF PIECES, SAID PIECES HAVING SEQUENTIAL UNIT SURFACES AREA DIFFERENCES AND BEING COMBINABLE TO FORM A COMPOSITE RECTANGULAR FIGURE. THE RECTANGULAR FIGURE THUS FORMED HAS A SURFACE AREA WHICH IS ONE-HALF THE TOTAL NUMBER OF PIECES TIMES THE SUM OF THE BEGINNING AND ENDING UNIT AREAS OF THE PIECES. AN ADJUSTABLE FRAME IS PROVIDED TO ACCOMMODATE LARGER AND SMALLER NUMBERED SETS OF PIECES FORMING CORRESPONDING LARGER AND SMALLER RECTANGULAR FIGURES. ALTERNATIVE PIECES HAVING THE SAME AREA BUT OF DIFFERENT SHAPE THAN INDIVIDUAL ONE OF THE PIECES MAY BE PROVIDED.
