Question

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.

Answer 1

The measure of the central angle is 120°.

So, the measure of the minor arc will be 120° (Since the measure of the central angle corresponding to a minor arc is also the measure of the minor arc).

The measure of the major arc will be 240° (Measure of major arc = 360° − Measure of the corresponding minor arc).
