Question

C 1. In the figures given below, check whether lis parallel to m. (a) 45°65° (b) 85° 85° (c) 93° 85° (d) 140°35° (e)100° 100° 80°
​

Answer 1

Answer:

(i) 125° +44° = 169⁰

1 is not parallel to m because sum of interior opposite angles should be 180º.

(ii) 75° +75° = 150⁰

1 is not parallel to m because sum of angle does not obey the property of parallel lines.

(iii) 57⁰ + 123° = 180°

1 is parallel to m due to supplementary angles property of parallel lines.

(iv) 98° +72° = 170⁰

1 is not parallel to m because sum of angle does not obey the property of parallel lines.
