The option (A) (1/2)mQRS = ∠T is correct because the measure of an inscribed angle is one-half the measure of its intercepted arc.
What is a circle?
It is described as a set of points, where each point is at the same distance from a fixed point (called the centre of a circle)
We have:
Rahim is constructing a proof to show that the opposite angles of a quadrilateral inscribed in a circle are supplementary.
From the central angle theorem:
(1/2)mQRS = ∠T because the measure of an inscribed angle is one-half the measure of its intercepted arc.
Thus, the option (A) (1/2)mQRS = ∠T is correct because the measure of an inscribed angle is one-half the measure of its intercepted arc.
