Theorem 10.8 : The angle subtended by an arc at the centre is double the angle subtended by it at any point on the remaining part of the circle.
Text Solution
Verified by Experts
In `/_\APO`
`OP=OA` (radius)
`/_OPA=/_OAP` (angle opposite to eqal sides are equal)
By exterior angle property,
`/_BOP=/_OPA+/_OAP`
`/_BOP=2/_OAP`
Similarly, in `/_\AQO`
...

The angle subtended by an arc of a circle at the centre is double the angle subtended by it any point on the remaining part of the circle.
Show that any angle in a semi-circle is a right angle. The following arc the steps involved in showing the above result. Arrange them in sequential order. A) therefore angleACB=180^(@)/2=90^(@) B) The angle subtended by an arc at the center is double of the angle subtended by the same arc at any point on the remaining part of the circle. c) Let AB be a diameter of a circle with center D and C be any point on the circle. Join AC and BC. D) therefore angleAD = 2 xx angleACB 180^(@)=2angleACB(therefore angleADB=180^(@))
