An arc is a fundamental geometric shape that is defined as a portion of a curve. It is commonly associated with circles, but it can also be a part of other curved shapes, such as ellipses and parabolas. Arcs are used in a variety of fields, including mathematics, physics, engineering, and architecture. They are particularly useful in geometry, where they are used to measure angles, calculate distances, and solve complex problems. One of the most important properties of an arc is its length, which is determined by its radius and the angle it subtends. The length of an arc can be calculated using the formula L = rθ, where L is the length of the arc, r is the radius of the circle, and θ is the angle subtended by the arc. Another important property of an arc is its curvature, which is the rate at which the curve changes direction. The curvature of an arc can be calculated using the formula κ = 1/r, where κ is the curvature and r is the radius of the circle. Arcs are used in a variety of applications, including architecture, where they are used to create arches, vaults, and domes. They are also used in engineering, where they are used to design gears, pulleys, and other mechanical components. In physics, arcs are used to describe the motion of objects in circular paths, such as planets orbiting the sun. In summary, an arc is a fundamental geometric shape that is defined as a portion of a curve. It is commonly associated with circles, but it can also be a part of other curved shapes. Arcs are used in a variety of fields, including mathematics, physics, engineering, and architecture, and they are particularly useful in geometry, where they are used to measure angles, calculate distances, and solve complex problems. The length and curvature of an arc are two important properties that are used to describe its shape and behavior.

Arc is a two-dimensional geometric figure that is composed of a curved line segment, or a circumference, between two points. An arc is generally defined as the portion of a circle that is bounded by two points on its circumference, or by two radii of the circle. The points that define an arc are known as its endpoints. The length of an arc is the measure of its circumference, usually given in units of length, such as millimeters or inches. The angle subtended by an arc is the angle between the endpoints of the arc, measured in degrees or radians. Arc length and angle subtended by an arc are related through the formula for the circumference of a circle.
