Answer»

(i) If two angles are complementary, then the sum of their measures is 90°

(ii) If two angles are supplementary, then the sum of their measures is 180°

(iii) Two angles forming a liner pair are supplementary

(iv) If two adjacent angles are supplementary, they form a linear pair

(v) If two lines intersect at a point, then the vertically opposite angles are always equal

(vi) If two lines intersect at a point, and if one pair of vertically opposite angles are acute angles, then the other pair of vertically opposite angles are obtuse angles.
