In geometry, an arc is defined as the portion or part of a circle’s circumference. Moreover, you can find this arc in other geometrical shapes like ellipse, but it refers to circles in most scenarios.

To neglect this mistake, it is also called a circular arc. For example, if a small curve line is drawn from point B to C, it is called an arc, and the distance between both curve points is known as arc length.

For a more precise understanding, let see the diagram listed below:
