How to put together a square How to make a square out of a rectangle?

1. There is a purple straight bar shaped block among the six building blocks, and some of the orange blocks and pink blocks are just inlaid to indicate that the two can be adjacent to each other.

2. Find the orange block and embed it in the narrow groove of the purple block.

3. Start to observe the bricks formed in the first two steps to form some weird irregular corners after docking, and observe that among the remaining four blocks, there is a dark green block that happens to be docked.

4. After the first three steps are completed, it is found that a raised straight bar shape is formed, and there must be a hole in the sphere to make up for it, and there is a green one in the remaining building blocks, which can be embedded.

5. The slot formed by the orange building block and the pink building block can be inserted, and finally there is exactly a slot left that can be inserted into the purple straight strip building block.

1. There are several ways to put together a square with a tangram.

There are seven ways to arrange a tangram square:

1. Use two identical triangles to form a square.

2. Use two identical small triangles to form a square.

3. Use a large triangle and two small triangles of the same size to form a square.

4. Use a large triangle and two small triangles and squares of the same size to form a square.

5. A large triangle and two small triangles of the same size and a parallelogram are put together to form a square.

6. Use a large triangle and a medium triangle and two small triangles of the same size to form a square.

7. The seven shapes are all put together into squares.

Second, how to spell seven square pieces of tangram.

1. Tangram is composed of two large triangles, a medium triangle, two small triangles, a square and a parallelogram.

2. Take a large square and place it at a right angle.

3. Take another piece of large triangle at a right angle and place it to the right.

4. Place a small triangle on the top right of the first large triangle, at a right angle to the left.

5. Place a square below the small triangle, and one side of the square is aligned with one side of the small triangle.

6. Take another small triangle, right angle upward, one side close to the square.

7. Place the parallelogram below the second small triangle.

8. Place the medium-sized triangle in the lower right corner.

Prepare 2 rectangles with a length of 10 cm and a width of 5 cm to form a figure, and there are two ways to carefully dig and spell.

1) The first spelling is to put the wide butt of two rectangles with a length of 10 cm and a width of 5 cm into a large rectangle, as shown in the figure below

2) At this time, the length of the new large rectangle becomes 20cm, the width is still 5cm, and the circumference becomes 50cm.

3) In the second spelling, the long butt of two rectangles with a length of 10 cm and a width of 5 cm is put together into a large square, as shown in the figure below

4) The new figure at this point is a large square with a side length of 10cm and a circumference of 40cm.

1. The long side of the two rectangles coincides, and it can be put together into a square with a side length of 10 cm.

2. The short side of each of the two rectangles coincides, and it can be put together into a rectangle of 20 cm and 5 cm of comfort.

3. A short side of a rectangle is on top of the middle spike of another rectangle, which coincides with a long side of another rectangle, and can be spelled into a T-shape.

4. The short side of a rectangle is on top of the short side of another rectangle, that is, the rectangle of this rectangle and the short side of another rectangle are in a straight line, which can form a "horizontal fold" shape.

The length of the rectangle is twice as long as the width, otherwise it will not be a square.

4 cubes can be put together into one (cuboid). The analysis process is as follows:

There are only two ways to spell a rectangle with 4 cubes:

Cubes are lined up to form a cuboid.

2. Swing 2 in each row, put 2 rows, and put together a cuboid.

Four cubes, you can't put together a large square loose ligand, and it takes 8 small cubes to put together a big cube.

The volume of the cube:

The volume of the cube edge length edge length edge length; Let the edge length of a cube be a, then its volume is: v=a a a or equal to a; First take the diagonal of the upper bottom surface, calculate, obtain, the root number 2 times the length of the edge, the edge of the face diagonal and its intersection, that is, the edge perpendicular to the upper bottom surface, and can form a right triangle, and the hypotenuse of this right triangle is the body diagonal, according to the Pythagorean theorem, obtain, the body opposition refers to the diagonal = 3 times the length of the edge.

The cube is a type of prism, and the volume formula of the prism is also applicable (to correctly distinguish between the volume diagonal and the face diagonal, the face diagonal is a concept in plane geometry and the volume diagonal is a concept in solid geometry) can also be calculated using the volume of the cube Base Area Height.

The two pie ridges are square, dusty, and orifice shaped into a rectangle, as shown below, Chunchun.

Basically, you can make two squares, and if you offset the same position in the horizontal and vertical directions, you can create one more square, and it will become 3 squares.

The two pairs of sides of the square are parallel and the four sides are equal. All four corners are 90 degrees; Diagonals are perpendicular, bisected, and equal, with each diagonal bisecting a set of diagonals.

A parallelogram with equal adjacent sides and right angles is called a square. A group of rectangles with equal sides is called a square, and a diamond at a right angle is called a square. The square is a special form of a rectangular stool and a special form of the diamond. Lease Nian.

If two identical rectangles can be combined into a square, the ratio of the length to width of the rectangle must be 2:1.

Therefore, the length and width of the rectangle are 4cm and 2cm, respectively.

When a square is formed, the side length of the square is 4cm, and its area is 16cm
