Circle geometry

Circle geometry are made up of lines and angles

From the given diagram, the sum of angles on the straight line GKH is 180 degrees

arcGM + arcMN = 180 degrees

Given that arcMN = 90 degrees, hence;

arcGm = 180 - 90
arcGM = 90 degrees

Hence the measure of the angle arcGM is 90degrees
