p1m1 is one of the 7 different frieze groups that there are. This group has a repeated vertical reflection pattern across a horizontal plane. In this applet you are able to move the points around and create a pattern. You can also change the color of the points. Try to create a fun design! Is there more than just reflection symmetry? If so what types of isometries can be seen on this applet? What happens when the points move closer to each other? Farther away from each other?
