There are 8 of the two squares. Just move two. It is enough to become a square with two side lengths.
-
Rotate the opposite sides of the two squares by 90° counterclockwise and clockwise, and you should be fine.
-
In the original "field" type, the two diagonal ones are removed for a total of 4 sticks, and then they are made into a square, and the four matches can be moved into the word "product" to form three congruent squares.
Remove 3 matches to form 6 congruent equilateral triangles. First, put 12 matches into a field character, then move the 2 matches in the upper left corner of the field character to the lower right corner, and then move the 1 match in the lower right corner to become a pinzi, and finally it becomes three small squares.
-
In the beginning, it is 2 squares made up of 8 toothpicks.
If you move it as shown in the figure above, it will become a "one" or "one" square.
The above is how to move 2 toothpicks from a square to 1 square.
A quadrilateral with all four sides equal and all four corners at right angles is called a square.
There is a set of rectangles with equal adjacent sides that are squares.
A parallelogram with equal adjacent sides and one corner at a right angle is a square.
A diamond with a right angle is a square.
A quadrilateral with diagonals bisected and equal, and diagonals perpendicular to each other, is a square.
A diamond with equal diagonals is a square.
-
Cut the two squares diagonally.
into four isosceles right triangles.
Right angled edges are put together.
Use the hypotenuse as the edge of the large square.
Is that so?
-
Three squares can be formed by overlapping two squares of the same size (four matches each) on top of each other. The specific pendulum is as follows:
First, as shown in the figure below, the first thing is to use four matches to spell out a square. Shouting town.
2. Then use the remaining four matches to form another square.
3. Then make one of the resistance into a square and move it diagonally down to the other.
Fourth, when moving to the position of Chang Zhiheng in the figure below, it can form three squares.
-
Preparation materials: 24 matches. Leather sails.
1. First of all, use 24 matches to form a hollow shape, 16 on the periphery and 8 on the inside, the specific arrangement is as follows.
<>3. After the top match is moved, turn the top match on the right side of the hail at the same 90 degrees.
4. Turn the bottom one of the leftmost matches at a 90-degree turn.
5. Turn the leftmost match at the bottom of the match to a 90-degree bend, so that two squares appear.
-
Fill the two matches in the middle on both sides, and add one on each sideThat is, up, down, left. On the right are two matches, which means that the length and width of the large square are twice as long.
I don't know if you understand that. I can't get a match to try it down.
Question (1), remove 2 matchsticks so that they contain two squares.
This is not easy for young students who don't like to use their brains.
In the process of placement, there are also many young students with active thinking, who have given correct answers through many practical operations.
These little students know that it is removed, and it is no longer placed.
After removing, it is shown in the following figure:
The 1st and 2nd roots can be removed at the same time, or they can be removed at the same time: 1 and 4; or 2 and 3; or 3 and 4
In question (2), move 3 matchsticks and arrange them into 3 squares.
In the actual operation, it is difficult for many young students.
This requires students to have serious reading skills, observation skills, spatial imagination skills, hands-on skills, and problem-solving skills.
Let the little students understand: it is to move and then place.
The move is placed as follows:
Of course, you can also move the other 3 matchsticks to place 3 squares.
Question (3), move 4 matchsticks and arrange them into 3 squares.
The difficulty has been further increased, and the difficulty of thinking has been raised.
Why is there such a difficult question? Parents think it's a bit incredible: this difficulty is comparable to the difficulty of junior high school mathematics, in fact, the reason why such questions appear in the textbook is to activate the thinking of primary school students and exercise their hands-on ability.
Still have to understand: move and then place.
The move is placed as follows:
Of course, you can also move the other 4 matchsticks like this to make 3 squares.
There is only one way. Two squares that are exactly equal together are a square. Move two? Just swap two for that. If you want to put together a big square with a side length of 2, tell you, impossible, you can tell.
Does it make sense? Try it, in turn, and start with a large square. It is impossible to move just two into two small squares.
-
Solution: Remove a matchstick from the top left and bottom right respectively to form two squares.
-
In the word Tian, any two adjacent crosses can be.
-
Since the size is different, it can only be a large square, completely covering the small one.

Of course not, because there are three people on it, and if you change one in the middle. Connect them and you'll call.
Hello landlord, your situation is more common, it is recommended to divide the cage, if you really want to close the cage you can do this: take a bath for the black spot (don't wash it, be sure to bathe in the sand), and then wash it for the snowball, and put them into a large container after washing (the basin, the foot basin, etc. can be big), add some sawdust in the container. Start observing. >>>More
