According to Wikipedia, there are several definitions of the word circle.
In mathematics, a circle is a closed shape with equal distances from its center to every corner. This distance is known as a radius. A circle can also be described as a closed curve, which divides a plane into two sections, interior and exterior. In other words, it’s a two-dimensional shape, which is round. Also, a circle can be defined by its circumference, which is the line that goes around its center. In technical terms, it’s the boundary of a figure known as a disc.
Another definition, according to Lumen Learning, describes a circle as a type of eclipse, where the radius is the same for all points. A circle is also defined as a plane figure, bound by one line, such that all the right lines drawn from the circumference to the center are equal.
The other meaning of a circle is a group of people with a shared profession, or shared interests, activities, or acquaintances.
For example: The knitting circle meets every second Friday of the month. Trust holds our circle of friends together.
As a verb, circle means revolving or drawing a circle around.
