Repeating circle

A repeating circle is like drawing the same shape over and over again so that it makes a pattern. It's like when you color in a circle and then keep copying it next to the first one, and then the second one gets copied over and over again in a row, making a line of circles that are all the same. Then, you take that same row of circles and copy it under the first one, and keep doing that until you have a big pattern of circles that all look the same. It's like a circle that is repeating over and over again in a predictable way to create a bigger and more complicated pattern.
