Converting from degrees to radians
90 deg = pi%2F2 radians
180 deg = pi radians

Complement of an angle + angle = 90 deg or pi%2F2 radians
Supplement of an angle + angle = 180 deg or pi radians

Complement of 2pi%2F9 = pi%2F2+-+2pi%2F9+=+5pi%2F18 radians or 50 degrees
Supplement of 2pi%2F9 = pi+-+2pi%2F9+=+7pi%2F9 radians or 140 degrees
