What you can do
- Six blocks: green triangle, blue rhombus, red trapezoid, yellow hexagon, orange square and tan rhombus; drag them from the tray or tap them.
- Blocks snap together edge to edge and turn in steps of 30° with the round handle or the R key.
- Cover the yellow hexagon with two trapezoids, three blue rhombuses or six triangles to show halves, thirds and sixths.
- Select several blocks to move, turn, copy or delete them together, and write or draw on the workspace with the pen.
- Show vertices as red dots or a dot grid, and download your pattern as a PNG, with a transparent background if you like.
