Reflection tessellation examples3/18/2024 ![]() ![]() If you're not sure, check off under the "Not Sure" column. ![]() You previously learned about three methods, check off the one you think is being used: TRANSLATION, ROTATION, or GLIDE REFLECTION. The next step is to decide which type or method of tessellation is being used. The first step is to sketch the shape that starts the tessellation. For each tessellation fill in the row on your worksheet. Your job is just to watch, the computer program will show you one tessellation, demonstrate how it is made, and then move on to the next tessellation shape on its own. ![]() The program will show you how each tessellation is made. You now will be watching ten different tessellations. Make sure that each person in your group has a worksheet and can see the computer screen. We will not be making animated tessellations, but it works well here for an introduction.įor this part you need to just sit back, grab your pencil and the worksheet chart that should have been handed out by your teacher. Glide Reflection Symmetry A tessellation possesses glide reflection symmetry if it can be translated by some vector and then reflected about that vector and remain unchanged. Try to identify a point of 6-fold rotational symmetry. Now that you have learned about three common types of tessellation, you will have the chance to use a program called TESSELMANIA! to further explore these ideas.įirst start by opening TesselMania! on your computer.Ĭlick on the center rectangle to move on. In the example below, point A is a point of 3-fold rotational symmetry, while point B is a point of 2-fold rotational symmetry. TesselMania! Introduction Tessellations by TesselMania! ![]()
