Answer:
which of the following is true for the given figure where o is the centre of the circle ?
∠ QPR = ∠QOR
∠ QPR = 2 ∠ QOR
∠ QPR = 1/2 ∠ QOR
∠QPR > ∠QOR
CONCEPT TO BE IMPLEMENTED
THEOREM :
The central angle subtended by two points on a circle is twice the inscribed angle subtended by those points.
EVALUATION
Here in the figure -
Central angle = ∠ QOR
The inscribed angle = ∠ QPR
We know that the central angle subtended by two points on a circle is twice the inscribed angle subtended by those points.
Thus we get
∠ QOR = 2 ∠ QPR
⇒ ∠ QPR = 1/2 ∠ QOR
FINAL ANSWER
Hence the correct option is
∠ QPR = 1/2 ∠ QOR
