Answer:
∠AOC is the central angle, inscribed angle is ∠ABC, circumscribed angle are ∠ABC,∠BAC,∠ACB,there is no exterior angle.
Step-by-step explanation:
Central Angle is formed by center of circle here o is the center of circle
∠AOC is the central angle.
Inscribed angle is the angle inside a circle
Here, inscribed angle is ∠ABC
Circumscribed are the angles formed at the circle
Hence, circumscribed angle are ∠ABC,∠BAC,∠ACB
Exterior angles are those lies outside the circle
Hence, there is no exterior angle.
