Question

prove that angle in the measure segment is Acute angle​

Answer 1

Answer:

we know that angle subtended by an arc of a circle at its centre is twice the angle subtended by it at any point of the alternate segment of circle. Since AB is minor arc and angle ACB is the angle formed by it in alternate segment. Therefore 2∠ACB = ∠AOB. => ∠ACB is an acute angle

Answer 2

Answer:

we know that angle subtended by an arc of a circle at its centre is twice the angle subtended by it at any point of the alternate segment of circle. Since AB is minor arc and angle ACB is the angle formed by it in alternate segment. Therefore 2∠ACB = ∠AOB. => ∠ACB is an acute angle.
