Which of the following statements are true (T) and which are false(F) (i) Angles forming a linear pair are supplementary. (ii) If two adjacent angles are equal, then each angle measures `90^@dot`. (iii) Angles forming a linear pair can both the acute angles. {iv) If angles forming a linear pair are equal, then each of these angles is of measure `90^@dot`.

Explanation

(i) True.(ii) False. It can be possible if they are a linear pair.(iii)False. In a linear pair, if one is acute, then the other will be obtuse(iv)True.
