What does a symmetrical pattern look like? If we draw a line through the center of our pattern, we can see that it is symmetrical. It’s the same on both sides. We can match the shapes from the center in the same order: two pink circles, two blue circles, and so on. Any pattern that is the same on both sides of the center is a symmetrical pattern.
