How to Use this Applet
If you click any one of the small triangles inside the large hexagon, this will create a large dot in that triangle. You can remove that dot by clicking again in the triangle.
In doing this you might create some symmetries (reflections and rotations), and if so you will see the symmetries described on the right, and also marked on the diagram.
You can show or hide the descriptions or the markings by ticking or unticking the small boxes at the top.
You can try to set up more and more difficult patterns and investigate their symmetries. This should help you gain insight into symmetry.
