Did you know that tangram shapes can be made from tangram shapes? Click the color bars and discover! Arrange a tangram shape from tangram shapes. Use the colored points to drag the shapes, and the corresponding sliders (in the same color) to rotate them. When you are done, you can hide the points clicking on the appropriate button.
