Answer 1

(i) If one angle of a linear pair is acute, then its other angle will be obtuse.
(ii) A ray stands on a line, then the sum of the two adjacent angles so formed is ${180}^0$.
(iii) If the sum of two adjacent angles is ${180}^{\circ }$, then the uncommon arms of the two angles are opposite rays.
