In these, you can cross matches:

1. Move three, make three squares.

2. Move four, make three squares.

3. Move two, make seven squares.

4. Remove two, leave two squares.

Make three identical squares from the pattern of 15 matches to the right by:

1. Removing three and moving two.

2. Removing three and moving three.

3. Removing three and moving four.

Use 13 matches to make this pattern of six idential triangles. Then remove three matches to leave three triangles.

This Star of David, made from 18 matchsticks, has six identical triangles and two larger ones. By moving two matches, change the figure so that it contains only six triangles.

Sixteen matches go into the making of these five identical saures. By moving only two matches, transform it into an array of four identical squares.

There are seven identical triangles in the pattern shown to the right. (There is also an eighth triangle with sides two matches long.) Move six matches to form six identical rhombuses (diamond shapes).

Make four equilateral triangles from only six matches. It can be done, without breaking any matches.

You'll need 12 matches to construct the pattern of two nested squares shown at right. Now trip these two problems:
1. Remove two of the matches and reposition six of the others in such a way that you are left with three identical squares.
2. Remove two matches and reposition four of the others so as to achieve the same result, namely three identical squares.

The design at left is made from 12 matchsticks. Move five of them so as to create a pattern consisting of three squares that are identical.

Where two stages are necessary, the first diagram shows the position of the matches after the first move, with matches still to be moved indicated in blue. The final arrangement is given below the first.
