Identify all the central angles and all the
arcs shorter than a semicircle for circle 0. help ASAP

Central angles: ∠AOB and ∠BOC
The shorter arcs are [tex]\widehat{AB}, \ \widehat{BC}[/tex].
Solution:
Given image is the circle.
Central angle:
The central angle is formed by two radii of the circle with its vertex at the center of the circle.
Central angles: ∠AOB and ∠BOC
Minor arc:
An arc shorter than a semicircle is called as a minor arc.
In the circle, the shorter arcs are [tex]\widehat{AB}, \ \widehat{BC}[/tex].
