The figure below is made up of 15 matchsticks. Please move two matchsticks to make them five same squares
The square in the upper left corner, the left side and the upper side are respectively placed above and below the middle, which becomes a square in the lower left corner. There is a large square on the right side, which includes four small squares
If you don't consider the big square, it should be right. I haven't thought of other moving methods yet
As shown in the figure, there are three squares made up of 12 matches. Can you move three matchsticks to make seven squares appear in the figure?
You can move the top one of the original upper square to the middle of the two lower squares, and move the left and right two of the upper square to the middle of the original left square. As shown in the figure below: A: you can move three matchsticks to make seven squares appear in the figure
Make a square with 8 matchsticks (as shown in the figure). Can you move the matchsticks (without reducing the total number of matchsticks) so that the area of the new figure is half the area of the square?
(the answer is not unique) as shown in the figure:

The following is to use 24 matches to make a circle, move 4 matches to make 2 squares become 3, and then move 8 matches to make the figure become 9 same squares
Finally, remove 8 matches and make the figure into 5 squares
First question: move 4 matches to make 2 squares become 3. First answer: This is a 4 × 4 outside + 2 × 2 inside circular square. Move two matches on a diagonal line of the outer square one step inward to get two 3 × 3 squares with intersection. Second question: move 8 matches to make the figure become 9 ones
Seven small squares made up of 20 matches. Now how to move three of them to make the figure into five small squares
As shown in the picture, move the red one to the pink one
The answer is clear enough! It's really hard to draw with computer
15 matches, 3 squares in a row, 2 squares in a row. How to move 3 matches to make the picture become 3 identical squares
Generally, the thinking of such a problem will be limited to how to move the match to change the shape, so you will find it difficult to solve the problem, or even no solution. The focus of this problem is the word "match". Why not say something like toothpick or thread? We know that the tail of the match is square. We just take out three matches and put them together, and then make the tail face us, Will become three identical squares, this problem can be solved~
How to move 2 matches so that there are 7 squares in the figure?
Just put the two on the top left corner in a square
Move three matches to change the square into three
There must be a picture, or I can't understand it! I'll choose the one with a clear picture!
Look at the picture

As shown in the picture, put the two pieces on the corner into the other mouth to form the character of Ota
There are four small squares and three large squares
