Q1 of 12 Page 111

If the measure of a central angle is 120°, find the measure of the corresponding minor arc and that of the major arc corresponding to this minor arc.

If the central angle is 120°


The measure of the corresponding minor arc


m(minor arc) = 120°


Measure of the major arc =


360° - measure of the corresponding minor arc


m(major arc) = 360°-120˚


= 240°
