Preview - Lattice Land: Polygon Exploration

The model: Lattice Land - Explore

  1. Open the file “Lattice Land – Explore”
  2. Click the “setup” button
    • You should see a black area with an array of yellow dots. This is called a “lattice.”
  3. Click “go”
  4. Select an “action”:
    • “draw-segment”
      • Click on any yellow dot in the black area. Next click on any other dot.
      • You will draw a line segment between the two dots.
    • “draw-polygon”
      • Click on any dot. Next click on any other dot. Then another, and another.
      • Continue linking dots.
      • When you click back on your first dot, you will have completed your polygon.
      • You can “check-area” for the last polygon you drew.
  5. You may clear all segments (“clear-segments”) or all polygons (“clear-polygons”), or reset everything (“setup”),
