A circle is a two-dimensional geometric object whose points are all the same distance from the center. The circle has four basic components. We will begin by identifying the components of a circle **visually** and **verbally**. The words are labels used to name the components depicted in red and are used to translate the geometric illustrations into verbal descriptions. Different words would be used if your native language is not English.Mathematical **equations** express **relationships**. There are mathematical equations that define the relationships between these components of a circle in various ways. These equations are used to find the lengths of the circumference, radius, and diameter of a circle as well as its area. We’ll look into these relationships beginning in the next blog.

Do you know of any other math terms that describe some part of a circle?
