Arc
Part of a circle connecting two points on the circle.
An arc is a segment of a curve that is formed by a portion of a circle or another curved shape. It is a part of a larger circle and can be defined as the measurement of the angle between two radii of the circle that intersect at the arc. The length of an arc is proportional to the measure of its corresponding angle and the radius of the circle.
Arcs are commonly used in geometry and trigonometry to calculate various properties of circles, such as circumference, area, and sector angles. They are also used in physics and other sciences to describe the motion of particles and their acceleration.
In addition to circles, arcs can also be found in other shapes, such as ellipses, parabolas, and hyperbolas. In these cases, they are often referred to as elliptical arcs, parabolic arcs, or hyperbolic arcs.
Overall, arcs play an important role in mathematics and its applications in various fields.
