Points N, P, and R all lie on circle O. Arc PR measures 120°. Circle O is shown. Line segment P N is a diameter that extends out
side of the circle to point Q. Line segment O R is a radius. Lines are drawn to connects point R to points P, O, N, and Q. Lines O R and N R are congruent. The length of P O is 5 and the length of R Q is 5 StartRoot 3 EndRoot. Arc P R measures 120 degrees. How does the measure of angle RNQ relate to the measure of arc PR? Angle RNQ is equal in measure to arc PR. Angle RNQ is half the measure of arc PR. Angle RNQ is twice the measure of arc PR. Angle RNQ is four times the measure of arc PR.
