Cross vs. Square

Home / Puzzle Playground / Puzzles / Tangrams /

The four identical pieces in the illustration can be used to form a Greek Cross shape as shown in the upper left corner and simultaneously to form a perfect square as shown below the Cross. Can you discover how to form both shapes using all the four pieces each time?

You are allowed to rotate the pieces but they must not overlap each other in the final shape.

Move the pieces dragging them, rotate the pieces clicking them.
