To move 4 toothpicks from 4 squares to make 3 squares, you can start by taking one toothpick from each of two squares and using them to create a new square. This will leave you with two squares. Then, take two toothpicks from one of the remaining squares and use them to join the two squares together, forming a larger square. This way, you have successfully moved 4 toothpicks from 4 squares to make 3 squares.
A square has 4 sides therefore 3 squares from 12 toothpicks will simply be three unconnected squares
break the toothpicks and you've doubled your amount of toothpicks
Move 3 lines "from" - do you mean 'remove 3 lines from' - or - move 3 lines to other places? Anyway, this all depends on the layout of the five squares.
Arrange the 9 toothpicks thus: 7 + 3
A sort of triangle of squares. Lay out 3 squares side by side using 10 matches. Take the middle match from the bottom row and use it and the other two to make a square based on the middle match of the top row.
Is this question supposed to have 12 toothpicks to make 4 squares and then move 3 toothpicks to make 3 equal sized squares? Answer depends on the restrictions. Just move 3 sticks from any square to form a straight vertical or horizontal line up of squares is one option if there is no restrictions other than the three resulting squares are equal sizes.

You make 3-D! Look... 6 squares in one cube and you can do that with toothpicks too!
You arrange 12 toothpicks into a large square, subdivided into four squares : 2 toothpicks on each side and four more, one each from the middle of the sides to the center of the large square. Now you have four (small) squares. Take away 2 adjacent toothpicks from the ones in the center, and you have 2 squares : one remaining small one and the large one that has the small one inside it.

Since every square has 4 sides and you only have 10 toothpicks, obviously you can't have the squares be separate. You will need exactly 2 toothpicks to overlap. Once you realize that, there are two shapes that are possible and can be rotated to make a total of 6 different solutions. A straight line (vertical or horizontal): = = = | | | | = = = Or an L-shape (forwards, backwards, and upside-down forwards and backwards): = | | = = | | | = = Sorry that these don't look quite right, the formatting is getting screwed up.
You can make three squares
