In Fig. 5.30, whi A. 1 + 5 = 180°

B. 2 + 5 = 180°

C. 3 + 8 = 180°

D. 2 + 3 = 180°

Answer :

1 = 3 (Corresponding angles)


3 + 5 = 1800 (Supplementary pairs)


So 1 + 5 = 180°


5 = 7 (Corresponding angles)


2 + 7 = 1800 (Supplementary pairs)


So 2 + 5 = 180°


1 = 3 (Corresponding angles)


1 + 8 = 1800 (Supplementary pairs)


So 3 + 8 = 180°


2 = 4 (Corresponding angles)


3 = 4 (Vertically Opposite angle)


So 3 = 2


Hence 3 and 2 are not supplementary pairs
