Draw a parallelogram with 8 sticks of the same length

With 8 sticks of the same length, you can create a parallelogram with equal sides.

i.e. diamond-shaped. Swing two small sticks on each side.

Within the same plane, there is a group of parallelograms with equal adjacent sides that are rhombuses, and quadrilaterals with equal sides are rhombuses, the diagonal of the rhombus.

Bisected perpendicular to each other and bisected by each group of diagonals, the rhombus is an axisymmetric figure, an axis of symmetry.

There are 2, i.e., the straight line where the two diagonals are located, and the diamond is a central symmetrical figure.

The rhombus is one of the special parallelograms.

All four sides are equal, i.e., diamond-shaped.

<> four small sticks of the same length can be put together to form a quadrilateral, i.e., a square before the state. A square, which is a special parallelogram.

One. That is, a group of parallelograms with equal adjacent sides and one angle is a right angle is called a square swim lead, also known as a regular quadrilateral.

It has all the characteristics of a rectangular and diamond-shaped.

Quadrilateral: A closed plane figure or three-dimensional figure enclosed by four line segments that are not on the same straight line in turn end to end is called a quadrilateral, which is composed of a convex quadrilateral and a concave quadrilateral. The quadrilateral obtained by God sequentially connecting the midpoints on any quadrilateral is called a midpoint quadrilateral, and the midpoint quadrilateral is a parallelogram.

The midpoint quadrilateral of the rhomboid is rectangular, and the midpoint quadrilateral of the rectangle is rhomboid, isosceles trapezoidal.

The midpoint quadrilateral is a diamond, and the midpoint quadrilateral of a square is a square.

Summary. Hello, with four small sticks you can build the first parallelogram, square,. If you don't want to wait for a stick, you can also make a trapezoid, and with four sticks of the same kind, how many different shapes can you build? Please draw a graph.

Hello, with four small sticks you can build the first parallelogram, square,. If it's a small stick that you don't want to wait, you can also pose in a trapezoidal shape, and I'll draw you the specific shape.

If the length of the stick is different, it can also be an irregular quadrilateral

A quadrilateral is a graph made up of four line segments, where for any two line segments, they are not collinear. Therefore, we need to consider the various combinations of quadrilaterals to make this wheel bend problem.

First of all, there is at least 1 quadrilateral that can be posed with 4 small sticks of the same length. This is because, take any 4 small sticks, and if they are not collinear, then you can connect them to form a quadrilateral. If they are collinear, then you will only get 3 line segments, and you will not be able to form a quadrilateral.

Secondly, we need to consider how many different types of quadrilaterals can be posed out by these 4 small sticks. There are several scenarios:

1.Parallelogram: If we place two small sticks together and then connect them with two other small sticks, we can get a parallelogram. Because the two sets of opposite sides of the quadrilateral are parallel.

2.Rectangle: If the three sticks are perpendicular to each other and the fourth stick is perpendicular to one of the others, the four sticks can form a rectangle. Because the adjacent sides of the rectangle are perpendicular.

3.Rhombus: If two rods intersect, and the four rods are of equal length, a rhombus can be formed. Because the four sides of the diamond are all equal in length.

4.Trapezoid: If two dull sticks are parallel, and the other two sticks are not parallel to the two sticks, you can form a trapezoid. Because of the two pairs of sides of a trapezoid, one is parallel and the other is not parallel but intersects.

Therefore, you can use 4 small sticks of the same length to pose the above four different types of quads. It should be noted that the above four types of quadrilaterals also intersect themselves, for example, the rectangle is a special parallelogram, which belongs to the type of quadrilateral. Therefore, the intersection needs to be removed during the calculation.

Without considering the intersection, 4 small sticks of the same length can be posed with at least 4 different types of quadrilaterals, namely a quadrilateral, a parallelogram, a rectangle and a rhombus. If you take into account the commonalities, the final number of different quadrilateral types is 3<>

Summary. You can move the three matchsticks on the far right and place them on the far left to form a 1 1 parallelogram, and then place them in turn to form three parallelograms of the same size.

Use 12 small sticks of the same length to form a parallelogram, and move 3 small sticks to make it into 3 parallelograms of the same size.

You can move the three matchsticks on the far right and place them on the far left to form a 1 1 parallelogram, and then place them in turn to form three parallelograms of the same size.

You can move the three matchsticks on the far right and place them on the far left to form a 1 1 parallelogram, and then place them in turn to form three parallelograms of the same size.

As shown below:

Analysis] This question mainly examines the mastery of the properties of parallelograms.

Because the opposite sides of a parallelogram are parallel and equal, two on the top and one on the bottom, and one on the left and one on the right, you can form a parallelogram.

1x2+2x2

6 (root) Two groups of quadrilaterals with opposite sides parallel to each other are called parallelograms.

1. Parallelograms belong to plane figures.

2. Parallelograms belong to quadrilaterals.

3. The parallelogram belongs to the center symmetry figure.

One on the left and one on the left, two on the top and bottom. You try to swing it and draw it again.

2 on the top, 1 on the left, 2 on the bottom, and 1 on the right.

Make parallelograms with 4 and 6 sticks of the same length, respectively, and draw a diagram.

A: You can build two different shapes. [Analysis].

This question tests the knowledge of squares and parallelograms.

The shape of four identical sticks is a quadrilateral, and because the four sides are equal, they can be built into a square or parallelogram.

Swing a parallelogram with small sticks of the same length, using a minimum of four small sticks. The following is a description of the specific placement method for reference:

Pose a parallelogram with small sticks of the same length, using a minimum of 4 small sticks.

Principle: Two sets of quadrilaterals with equal opposite sides are parallelograms.

If you have any questions, please ask; If you are satisfied, thank you!

A parallelogram has 4 sides.

Use four small sticks of different lengths to make sure you can't spell out a diamond.

Four small sticks of the same length can enclose several quadrangular rulers.

Four small sticks of the same length can be said to be enclosed into a quadrangular mausoleum bridge on the surface, and there are two cases of subdivision of the quadrilateral

1. If the four small sticks are perpendicular to each other and the opposite sides are parallel to each other, they can be enclosed into a quadrilateral, which is a square;

Second, if the four small sticks are not perpendicular to each other, but the opposite sides are parallel to each other, the quadrilateral is a diamond. So it can be said that four small sticks of the same length can enclose two quadrilaterals.

Four small sticks of different lengths can be arranged in a triangle.

Or quadrilateral. The three sides of a triangle must follow the principle that the sum of the two sides is greater than the third side, so that the triangle can be posed, otherwise the triangle cannot be spelled. The four small sticks can be put together into any quadrilateral, and they can also be put together into a trapezoid, which is a quadrilateral with two parallel sides above and below.

The Nine Palaces puzzle tricks are as follows:

1) The two small squares in the middle and to the right already contain the number 1. The little cell on the left doesn't have the number 1 yet. As you can immediately imagine, the number 1 must appear in an empty space in the small box on the left.

At the same time, because the first two rows of the grid already have the number 1, the number 1 can only be placed in the empty position in the third row of the small grid on the left.

2) Look at the rest of the lattice. If you look at the 3 small cells in the middle, you will see that the number 2 is similar to the number 1 just now. The number 2 is missing from the upper cell, and the number 2 appears in the 4th and 5th columns, respectively, in the lower two small cells.

So the number 2 can only appear in an empty position in column 6 of the small cell above, but it is not possible to determine which one it is. At this point, Chada has to further determine the position of the number 2 based on the situation of the other rows.

3) The number 2 already appears in the third row, so the number 2 cannot appear in other positions in the third row. In this way, it can be determined that the number 2 should be filled in the second row of the sixth column.
