The roti canai puzzle

Ayu stands at a roti canai tray in the market. The cook cuts a square of dough corner to corner, and two triangles fall apart. Ayu pushes the two triangles together and a square appears again. Wei grins and asks, 'Which shapes can fit together to make a new shape, and how do we draw it the same on paper?' By the end I can put shapes together, cut a shape in more than one way, and draw the same figure on a grid.
