Solve a tangram in three moves

All seven go in, lying flat. No overlaps, no pieces left over. That is the whole rule.

The two large triangles fill half the area, so they decide the shape. Find where they go, then fit the small ones.

It is the only piece with a mirror image. If a figure will not close, turn it over.

Seven pieces. Thousands of figures.

选Pieces that slide back into a perfect square with no gaps.
