What does a tangram look like, what is a tangram

Tangram. It is also known as a tangram, a wisdom board, and a Luban lock.

Nine Links is also a traditional Chinese educational toy. As the name suggests, a tangram is made up of seven plates, which are five isosceles right triangles (two minor triangles, one medium triangle, and two large triangles), a square, and a parallelogram.

The full pattern is a square.

Tangram evolved from the Song Dynasty's Yanjig, designed by applying the mathematical principle of "Pythagorean shape, triangle misalignment", these seven boards can be spelled into many graphics, according to statistics, more than 1,600 kinds, players can spell it into a variety of characters, animals, bridges, houses, towers and other images, can also be some Chinese and English letters or geometric figures.

Tangram is an invention of the ancient Chinese working people, which was widely circulated among the people in the Ming and Qing dynasties, and spread abroad in the 18th century. It can inspire children's intelligence, cultivate children's observation, imagination, shape analysis and creative logic, and also help children recognize colors, geometric shapes and basic mathematical concepts.

According to Lu Yiyan's "Leng Lu Miscellaneous Knowledge" in the Qing Dynasty, he said: Song Huang Bosi feasted on a few pictures, with a few square seven, the long sections were coherent, and they were derived into twenty-five bodies, becoming sixty-eight. A few pictures of the Ming Yan butterfly are adapted to the shape of the Pythagorean to make a triangular phase misshape, such as butterfly wings.

Its formula is three, its system is six, its dozens have three, and its changing formula is more than one hundred. Recently, there are tangrams, its formula is five, its number is seven, and its variation is more than a thousand. The shape of the body and objects, changing at will, and covering the game, is enough to dispel the boredom and break the silence, so the world likes it.

Now the tangram is cut into five small Pythagorean shapes by a square, and it is pieced together into various things, such as figures, animals and plants, pavilions, cars, boats, bridges, etc., which can be played by one person or by many people. The use of tangram puzzles can elucidate a number of important geometric relationships, the principle of which is the "principle of complementarity between entry and exit" in ancient arithmetic.

Tangram is a mind game, as the name suggests, a jigsaw puzzle is made up of seven boards, the complete pattern is a square, including two small triangles, a medium triangle and two large triangles, a square and a parallelogram.

These seven boards can be put together into many figures, such as: triangles, parallelograms, irregular polygons, and can also be put together into various figures, images, animals, bridges, houses, towers, etc.;

Tangram is more popular, because of its simple structure, rich colors, especially suitable for children, tangram can not only help children improve intelligence, but also teach children to recognize colors, guide children to understand the segmentation and synthesis of graphics, and then enhance children's hand intelligence, patience and observation;

Many adults also like the game of tangrams, if there are more sets of tangrams, they can also be used to spell out specific patterns, which can be used to develop intelligence and pleasure at the same time, so it can be passed down to this day;

Tangram originated in the Song Dynasty, also known as Tangram, wisdom board, is a Chinese folk intellectual toy, it is evolved from the Song Dynasty banquet, began to be an indoor game between the literati, and later evolved into a puzzle board play in the folk, Tangram is the invention of the ancient Chinese working people, the Ming and Qing dynasties were widely circulated among the people, and in the 18th century, it spread to foreign countries, and immediately aroused great interest, some foreigners played it all night, and called it Tang Tu, which means a puzzle from China.

Tangram is made up of seven boards, which are a square, two large triangles, a diamond, two small triangles, and a medium triangle.

Tangrams are mainly composed of three types of shapes, namely triangles, squares, and parallelograms. When composing a tangram, there are also different requirements for the number of each type.

For example, the triangle in a tangram needs to be an isosceles right triangle, in which two small triangles, one medium triangle and two large triangles are required. Then combine it with squares and parallelograms to form a tangram.

The origin of the tangram

As an intellectual toy, tangram was mainly used in the Northern Song Dynasty. During the Northern Song Dynasty, there was a man named Huang Bosi, who was very hospitable, and his home was often full of guests, so in order to let everyone have a place, he designed six rectangular tables.

When it comes to the banquet, according to the number of guests who come, the table is put together into different shapes to meet the needs of everyone and make it more convenient.

By the time of the Yuan Dynasty, many craftsmen used Huang Bosi's Yanji drawings to innovate with wooden blocks. There is a person named Yan Cheng, according to the principle of Yan Jitu, he tried to add triangles to the figure for the first time, and designed about thirteen graphic cases. When these figures are combined, they form a shape that resembles butterfly wings, and thus form a butterfly score.

Tangram is seven plates of different colors and sizes, including five triangles, a square, and a parallelogram, these seven boards can be put together into a variety of graphics, and it is a puzzle building block invented by the ancient Han working people.

1. How to playTangram is composed of seven plates of different shapes and sizes, which can be put together into many shapes, such as squares, triangles, parallelograms, etc., which were used by the ancients to entertain and relieve boredom a long time ago, and are now widely popular among primary school students as educational toys. States and redundancy.

2. SignificanceNowadays, tangram is used in teaching. According to different spellings, it can be put together into a variety of geometric shapes and images, such as ships, sails, houses, pistols, etc. It helps to diverge thinking, develops imagination and creativity, and is not only entertaining, but also educational.

The origin and story of Tangram are:

1. The origin of tangram is:The original face of the tangram is "Yan Ji Tu", and Yan Ji means a table for greeting guests to a banquet.

2. The story of Tangram is:In the Song Dynasty, there was a man named Huang Bosi, who was very fond of all kinds of geometric figures, so the furniture in the house was also "quite distinctive".

One day, he invited guests at home, the table for the guests was 6 small tables he designed to put together the "banquet table", during the banquet, the position can be adjusted according to the number of guests, and later added a small table, separate combination, endless changes, quite practical and interesting.

On this basis, later generations transformed Yanji into 7 planks made of wooden boards. At the end of the Ming Dynasty and the beginning of the Qing Dynasty, people often used it to celebrate festivals and entertainment, spelling out various auspicious patterns and words, and were called "tangrams" and "wisdom boards" by people.

In the 18th century, the tangram was spread abroad, and it immediately aroused great interest among foreigners, who played it day and night, calling it "tangram", which means "puzzle from China".

Tangram. Help your child recognize geometric shapes, sizes, lengths

The tangram consists of seven plates, and the complete pattern is a square: five isosceles right triangles (two small triangles, one medium triangle, and two large triangles), one square, and one parallelogram.

When children play tangrams, the most basic thing is to recognize the shapes of triangles, squares and parallelograms, and through playing, they can also come into contact with shapes such as rectangles and trapezoids.

There are five isosceles right-angled triangles in the tangram, and through comparison, children can easily grasp the size of the triangular plank and the length of the sides, and establish a preliminary concept of "quantity".

The square and the two smallest triangles in a tangram (triangle 1 and triangle 2 in the image below) can be spelled together to form a new triangle.

Stitched as shown below:

The tangram consists of five isosceles right triangles (two small triangles, one medium three-rolled large triangle, and two large zhi triangles), one square, and one parallelogram. And these seven boards can be put together into many shapes (more than 1600 kinds), such as: triangles, parallelograms, irregular polygons, players can also spell it into a variety of characters, images, animals, bridges, houses, towers, etc., can also be liquid lead some Chinese and English letters.
