Step-by-step explanation:
(c) As, 123+ 57 = 180
Since , they form a pair of co interior angles
So, L is parallel to M.

Answer:
(a) not parallel (b) not parallel (c) parallel (d) not parallel
Step-by-step explanation:
(i) 125 +44 =169
l is not parallel to m because sum of interior opposite angles should be 180 .
(ii) 75 +75=150
l is not parallel to m because sum of angle does not obey the property of parallel lines.
(iii) 57 +123 =180
l is parallel to m due to supplementary angles property of parallel lines.
(iv) 98 +72 =170
l is not parallel to m because sum of angle does not obey the property of parallel lines
