What is an Arc?

An arc is one of the portions of a circle. An arc can be a portion of some other curved shapes like an ellipse but mostly refers to a circle. To avoid all the possible mistakes, it is also known as circular arc.

A straight line that could be drawn by connecting the two ends of the arc is known as a chord of a circle. If the length of an arc is exactly half of the circle, it is known as a semicircular arc.

Naming:

An Arc is named based on its endpoints.

Arc length:

The arc’s length is computed in distance units, such as centimeters

Angle Measure:

The angle that is created by the arc at the middle of the circle is nothing but the angle measure.

Distinguish between an arc and a radius.
