    Angle 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.

    The measure of an inscribed angle is how related to its intercepted arc?

    I understand the theorem but how do find the length?

    Read the part of the attachment that says that the measure of the inscribed angle is ...... ? What comes next?

    1/2 the measue of the arc

    so multply it by two?

    Yes. So if angle R is 23, what is the measure of arc NQ ?

    do its 46?

    Yes. Next, do you see that central angle O cuts off the same arc that angle R did?

    Right so 23?

    No, 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?

    No, that was the inscribed angle. We're talking central angles.

    There 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.
