To do:

We have to fill in the given blanks.

Solution:

(i) If two angles are complementary, then the sum of their measures is $90^{\circ}$.

(ii) If two angles are supplementary, then the sum of their measures is $180^{\circ}$.

(iii) Two angles forming a linear 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.
