What is a Tangram?
A tangram is a Chinese puzzle made with the help of geometric shapes. Tangrams can be made by cutting colorful sheets into five triangles, a square, and a parallelogram. These seven geometry shapes can be merged to form several shapes. The seven individual tangram pieces are called tans. When the pieces of a tangram are arranged together they display an amazing variety of forms and personify many numerical and geometric concepts. Tangram pieces are broadly used to solve puzzles. All seven pieces can be fit together to form a square. Observe the following figure that shows a sevenpiece tangram.
In the figure given above, the triangles with the numbers, 3 and 7 are equal and small as compared to the other triangles. Triangles with numbers 4 and 5 are large triangles and the triangle with number 2 is a medium triangle. The piece labelled as number 1 is a parallelogram and the one with number 6 is square. As we can see all seven pieces fit together and make a big square.
Why Do We Use Tangrams?
Like building blocks, tangrams can develop problemsolving and logical thinking skills, perceptual reasoning, visualspatial awareness, creativity, and many mathematical concepts such as congruency, symmetry, area, geometry, and perimeter. They help kids learn geometric terms and develop stronger problemsolving abilities. Children can perform better in tests of basic arithmetic with the help of tangrams. There are over 6,500 shapes and pictures that can be created using a tangram puzzle.

Solved Examples on Tangrams

Example 1: Becky wants to know the use of tangrams. Can you solve her query?
Solution: Tangrams can be used for various purposes like developing problemsolving and logical thinking skills, perceptual reasoning, visualspatial awareness, creativity, and many mathematical concepts such as congruency, symmetry, area, geometry, and perimeter. 
Example 2: What are the seven shapes that make up a sevenshaped tangram?
Solution: The tangram is a simple set of seven geometric shapes made up of five triangles (two small triangles, one medium triangle, and two large triangles), a square, and a parallelogram. 
Example 3: What are tangram squares?
Solution: Tangram is a traditional Chinese puzzle that is made up of a square cut into seven pieces (one parallelogram, one square, and five triangles) and they can make a different design according to their arrangements. When all 7 pieces are combined together, they form a square which is called a tangram square.
FAQs on Tangrams
What do Tangrams Look Like?
A tangram is a puzzle that includes two big triangles, one medium triangle, two small triangles, one square, and a parallelogram. When all these shapes are joined together, it forms a square.
What is the Difference Between Tangrams and Pattern Blocks?
Tangrams are geometric puzzles having geometric shapes that contain two large triangles, one medium triangle, two small triangles, one square, and one parallelogram, whereas, pattern blocks are a group of six shapes in six colors  green triangles, orange squares, blue parallelograms, tan rhombuses, red trapezoids, and yellow hexagons.
What are Tangram Rules?
There are some basic rules of tangrams that define its properties:
 Tangrams must have all seven pieces.
 All pieces of tangrams should be kept flat on a surface.
 All pieces of tangrams should touch each other.
 All pieces of tangrams should be arranged in such a manner that they should not overlap each other.
 Pieces can be rotated and can be flipped to make the desired shape.
