AB is a chord of a circle whose centre is O. if P is any point on the minor arc AB prove that angleAOB+ 2angleAPB=360
Dear Student,
Please find below the solution to the asked query:
We form our diagram from given information , As :
Here , AB is a given chord .
We know : 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 .
So,
Reflex AOB = 2 APB ---- ( 1 )
And
Reflex AOB + AOB = 360 ( Angle around the center of circle )
Substitute value from equation 1 and get
AOB + 2 APB = 360 ( Hence proved )
Hope this information will clear your doubts about Circles.
