Part of the circumference of a circle. Or part of any curve. See an arc in action (drag the points): The arc length is: L = θ × r (when θ is in radians) L = θ × π 180 × r (when θ is in degrees)

Jul 23, 2025 · Arc is a segment of the circumference of a circle or any curved shape. An Arc in geometry is any smooth curve connecting two specific points. Arc is a smooth curve linking these endpoints. …

The arc of a circle is defined as the part or segment of the circumference of a circle. A straight line that connects the two ends of the arc is known as a chord of a circle. If the length of an arc is exactly half …

To make an arc, you either need a chord or a central angle. A chord is a line segment that joins any two points on a circle. A central angle is an angle between any two radii of the circle. For instance, the …

The length of an arc can be calculated using different formulas, based on the unit of the central angle of the arc. The measurements of the central angle can be given in degrees or radians, and accordingly, …

Aug 8, 2023 · In mathematics, an arc represents the boundary portion of the circumference of a circle. The term arc is used in the condition of the circle and other curve shapes.

Arcs are often studied in geometry within the context of arcs of a circle. On a circle, you can think of an arc as a part of the circumference of the circle, as shown in the figure below.

What is the Meaning of Arc? In Mathematics, an arc means, a part of a curve or the portion of a circle. The straight line joining the ends of the arc is called the chord of the circle.

Dec 3, 2025 · In a graph, a graph arc is an ordered pair of adjacent vertices. In particular, an arc is any portion (other than the entire curve) of the circumference of a circle.
