*COIN-MOVING PUZZLES 407 shows how to solve it. Figures 6{9 show a few of the other puzzles we have designed. The last two puzzles involve labeled coins. Figure 5. A di cult puzzle on the square grid. The optimal solution uses 18 moves, each of which places a coin adjacent to two others. Figure 6. Another puzzle on the square grid. The optimal ...*41. The first column needs a triangle, and the second row needs a circle. The bottom right corner must be a square because all other rows and columns already contain a square. That means the bottom of the second column must be a triangle, and then a circle is needed right above it. Finally, it is clear that the shaded space must be a triangle ... These make good tile patterns or patchwork quilts! Shapes that tessellate ... Squares and triangles - There are two ways to mix squares and triangles in the same pattern. Most AutoCAD drawings are composed purely and simply from these basic components. A good understanding of the Draw commands is fundamental to the efficient use of AutoCAD.
