Definition

A circular arc is a portion of the circumference of a circle.

Description

Circular arcs are segments of a circle's circumference, used extensively in design, architecture, and engineering to create curved structures and paths. The length of an arc is determined by the central angle and the circle's radius, calculated using the formula 

L = rθ

where θ is in radians. Understanding circular arcs is crucial in math education as it introduces students to the concept of radians and angular measurement, which are foundational for trigonometry and calculus. Exploring circular arcs helps students develop spatial awareness and problem-solving skills, which are essential for advanced mathematical studies and practical applications.
