Question

Angle subtended by an arc at the centre of the circle is double​

Answer 1

Answer:

Check the solution below.

Step-by-step explanation:

Theorem: The angle subtended by an arc of a circle at its centre is twice of the angle it subtends anywhere on the circle's circumference. The proof of this theorem is quite simple, and uses the exterior angle theorem – an exterior angle of a triangle is equal to the sum of the opposite interior angles.
