Angle mn'o is formed by segments mn and no on the coordinate grid: a coordinate plane is shown. angle mn'o has vertices at negative 4 comma 4 and negative 2 comma 2 and negative 4 comma 1 and measures 71.57 degrees. angle mn'o is rotated 180 degrees counterclockwise about the origin to form angle m’n’o’. which statement shows the measure of angle m’n’o’? a. m∠m’n’o’ = 90 degrees b. m∠m’n’o’ = 180 degrees c. m∠m’n’o’ = 2 × m∠mn'o d. m∠m’n’o’ = m∠mn'o
