angle mno is formed by segments mn and no on the coordinate grid below:

a coordinate plane is shown. angle mno has vertices at negative 4 comma 4 and negative 2 comma 2 and negative 4 comma 1 and measures 71.57 degrees.
angle mno is rotated 180 degrees counterclockwise about the origin to form angle m′n′o′. which statement shows the measure of angle m′n′o′? (5 points)

m∠m′n′o′ = 2 × m∠mno

m∠m′n′o′ = m∠mno

m∠m′n′o′ = 180 degrees

m∠m′n′o′ = 90 degrees
