We know that the sum of supplementary angles is  180^{\circ} and the sum of complementary angle is 90^{\circ}.

(i) Sum of the angles is :    65^{\circ}\ +\ 115^{\circ}\ =\ 180^{\circ}. Hence these are supplementary angles.

(ii) Sum of the angles is :    63^{\circ}\ +\ 27^{\circ}\ =\ 90^{\circ}. Hence these are complementary angles.

(iii) Sum of the angles is :    112^{\circ}\ +\ 68^{\circ}\ =\ 180^{\circ}. Hence these are supplementary angles.

(iv) Sum of the angles is :    130^{\circ}\ +\ 50^{\circ}\ =\ 180^{\circ}. Hence these are supplementary angles.

(v) Sum of the angles is :    45^{\circ}\ +\ 45^{\circ}\ =\ 90^{\circ}. Hence these are complementary angles.

(vi)  Sum of the angles is :    80^{\circ}\ +\ 10^{\circ}\ =\ 90^{\circ}. Hence these are complementary angles.
