What is an arc?

• The bow of a circle or arc is defined as the part or member of the circumference of a circle.

• You can describe the bend of a rainbow as an arc. In calculation, an arc is one section of a circle, but in life, you can use the word to mean any twisted shape, like the bow of a ballerina's arm or the graceful arc of a flowering vine over a kiosk.
