With this tool, you can explore how to decompose shapes and recompose them to make other shapes. You can draw and cut shapes and also use slides, turns, and flips to move pieces around.
If you are using one of these browsers, it is likely that you do not have
your browser's menu.
Create a polygon with at least five sides. Then, place at least three cut lines across the figure. (Be sure that some of the cut lines overlap.) Mix the pieces up with the Mix Up button.
For a slightly more advanced exploration, try this: Create a parallelogram. Draw a cut line from one vertex that is perpendicular to the opposite side, then hit the Cut button. Rearrange the pieces to form a rectangle.
