Types of Arcs
A circle is divided into two sections by an arc, as you must have observed.
- Minor Arc
- Major Arc
- Semi Circle
Minor arc of a circle
A circle’s minor arc is essentially less than half of the circle’s overall arc. Blue color curve in the following figure is the minor arc in the circle.
Major Arc of a Circle
The major arc of the main circle is the arc that extends more than half of the circle. Red color curve in the following figure is the major arc in the circle.
Semi Circle
A semicircle is described in geometry as a half circle generated by cutting a circle in half. A line passing through the centre and touching the two extremities of the circle creates it. This line is known as the circle’s diameter.
Arc of a Circle
Arc of a Circle is a part of the circumference of a circle or we can also say the Arc of a Circle is some percentage of the circle’s circumference. As we know, a circle is defined as a two-dimensional geometrical object where all the points are equidistant from the center and the distance measured around the circle is known as a circumference and some portion of the circumference taken at a time is known as the Arc of a Circle.
In this article, we will learn the Arc of a Circle in detail, including its definition, types, and arc length formula. Other than that we will also discuss the angle subtended by an arc and the theorem related to this angle as well.
