This task provides an overview of using the Geometry tiles. Below are the topics covered.
- Working with Polygons - rotating, flipping, cutting, and more.
- Creating custom polygons
- Joining Polygons
- Tessellations with Pentagons
- 3D Solids
- Using the ruler and protractor
- Working with Penrose Tiles, Tantrix Tiles, Fractals, and Kolam Tiles
- Geometric Constructions
Rotations and Snapping Polygons
Use the custom polygon to create a polygon of any size with any number of vertices. Click on an edge to add a vertex and click on a vertex to remove it. The vertices snap to grid lines as well. Select "Fix Vertices" from the toolbar to prevent any more changes to the custom polygon.
Select multiple polygons and then click "Join" to create a combined Polygon.
Regular pentagons don’t tessellate, but there are 15 types of irregular pentagons that do – the last of which was only discovered in 2015. Here is one example.
Use the polygons to construct a net of a 3D object. Not all creations will be a valid polyhedron net. Below are some examples using squares. Click here to see some other examples.
Click "Unfold" or use the slider to unfold the polyhedron back into a net. Once unfolded, click "Unfold" again to separate the net back into individual polygons.
Using the grid background with the custom polygon can be helpful in creating nets.
Ruler and Protractor Tool
Select a tool and click "Flip" to reverse the direction of the numbers on the tool.
Patterns and Art
Penrose Tiles, Kolam Tiles, Fractals, and Tantrix Tiles
See the Polypad's below for an examples of how these tiles can used to make all sorts of designs!
Create a line or a polygon and then click on the three dots to see it's attributes.
When selecting a shape, a variety of construction options appear at the bottom of the canvas.
Use the "Invisible" option to hide parts of a construction.
