Best ResponseYou've already chosen the best response.1Angle R is an inscribed angle of a circle. Use the attached theorem to get the measure of the arc it cuts off. The intercepted arc is in blue.

Best ResponseYou've already chosen the best response.1Yes. So if angle R is 23, what is the measure of arc NQ ?

Best ResponseYou've already chosen the best response.1Yes. Next, do you see that central angle O cuts off the same arc that angle R did?

Best ResponseYou've already chosen the best response.1No, the central angle is not 23. On the previous problem, what did we say is the measure of the central angle of a circle in relation to its intercepted arc?

Directrix

Best ResponseYou've already chosen the best response.1No, that was the inscribed angle. We're talking central angles.

Best ResponseYou've already chosen the best response.1There is a little bit more to it. You don't know that the angles are congruent right off the bat. Look at the two congruent chords of the circle that go with the arcs cut off by the two central angles. Because in a circle, congruent chords have congruent arcs and the two central angles cut off congruent arcs, their measures are the same.
