| Construct a parallelogram, using Parallel Line in the Construct menu. |
|
| Construct a random shape on the left side of the parallelogram. |
|
| Select D and then C, and Mark Vector "D->C" in the Transform menu. Then
select all of the random shape and Translate it By Marked Vector using the Transform
menu. (Vector is the name for a segment with a given length and a given direction.) |
|
| Construct a 2nd random shape on the top of the parallelogram. |
|
| Mark D to A as a vector, and translate the 2nd random shape. |
|
| Select the vertices of your polygon in consecutive order and Construct Polygon Interior |
|
| Translate the whole polygon (vertices, sides and interior) by a vector DC and then
by a vector DA to create a tessellation. Use different colors for adjacent polygons.
Drag any point to change your tessellation. |
You may download and experiment with the sketch, or try a JavaSketchpad version.
