WebSince the size of the central angle of an arc determines its size, we define major and minor arcs in terms of their central angles. If the central angle is greater than 1 8 0 ∘, then the arc is major. If the central angle is less than 1 8 0 ∘, then the arc is minor. If the central angle is equal to 1 8 0 ∘, then the arc is semicircular.
