Tangram puzzle
Seven pieces. Infinite shapes. An ancient Chinese puzzle that's still teaching kids about geometry today.
Tangram puzzle
Drag the seven pieces. Tap one to select, then rotate or flip it. Try to fill the cat outline!
Tangram is an ancient Chinese puzzle: seven pieces — five triangles, a square and a parallelogram — cut from a single square. With them you can build hundreds of silhouettes.
The seven pieces
- Two big right triangles
- One medium right triangle
- Two small right triangles
- One square
- One parallelogram
All seven cut from one bigger square. Together they always cover exactly that square's area — no matter what shape you arrange them into.
Tangram fact
The parallelogram is the only piece that needs flipping (mirroring) to make some target shapes. The other six only need rotation.
What it teaches
- Composing larger shapes from smaller ones.
- Recognising rotations and reflections.
- Conservation of area — same pieces, different shapes, same total area.
- Spatial reasoning — picturing how a piece will fit before you place it.
