    a coterminal angle is an angle that is obtained when you either subtract or add the angle with 360 degrees :)

    example: Let's say we have A = -200 degrees, find the positive and negative coterminal angle In this case, the positive coterminal angle is Coterminal angle = -200 + 360 = 160 degrees Coterminal angle (negative) = -200 -360 = -560 degrees are you understanding it now bit by bit? :)
