If the transversal cuts across parallel lines (the usual case) then exterior angles are supplementary (add to 180°). The pair of angles must have equal angle measures and at the same time, add up to 180 ∘, hence the name of the angle. Thus, 145° and 40° are not supplementary, their sum is not equal to 180°. So in the figure above, as you move points a or b, the two angles shown always add to 180°.
