How to Make Tangram?


  • Basic Rules of This Puzzle Game –
    1. To create any shape, we must use all 7 pieces.
    2. All the pieces must lay flat on the floor while creating shapes.
    3. Pieces must be in touch with each other, and none of the pieces may overlap while forming any shape.

Over 6,500 (six thousand five hundred) different tangram problems have been discovered from the 19th century.

For Example:

If we want to create House from tangrams, we can arrange all pieces as below –

tangram house

By using all pieces of tangrams, we can create various shapes such as:

  • Objects (House, car, pen, etc.)
  • Birds
  • Animals
  • Shapes (Square, rectangle, triangle, etc.)
